Alarm reports

When alarm reports are e-mailed, set this option to 1. E-mail address set. When alarm reports are e-mailed, set the SMTP name (ex : smtp.yourisp.com). Contact your ISP (internet service provider) for the correct entry if needed.

system password

Password Setup  to set the system passwords. For password entry, the system allows eight users to be defined. Each user can have a: • Unique alphanumeric name (up to 10 alphanumeric characters) • Password entry of up to eight digits (using 0 ~ 9, # and • Password level *) The IN level password is used by the System Installer for system programming. The SA or SB level password cannot access the IN level programs. The reverse type (white on black) just beneath the Description heading is the program access level. You can only use the program if your access level meets or exceeds the level the program requires. (SA level password can access to SA or SB programs, and SB level password can access to SB programs only.)

Host Configuration Protocol

DSX system to be a Dynamic Host Configuration Protocol (DHCP) client. If the installation site has a DHCP server, this means that the site server can automatically provide the DSX with the following important network settings: • IP Address (the network address of the DSX system). • Subnet Mask (that allows the site server to differentiate internal LAN from external internet addresses). • Router Address (the address of the site router that handles external internet traffic). • Domain Name Server (DNS) Address (the servers that convert domain names [like necdsx.com] to their numeric IP addresses). DHCP Modes The DSX can operate as a DHCP client in either of two modes: DHCP or DHCP with Manual IP. • DHCP • When the DSX is initially connected to the installation site LAN, it requests the site DHCP server to provide (lease) an IP address from it’s available pool of addresses.  The DHCP server also provides the Sub- net Mask, Router  Address, and the DNS address.  Additionally, the DHCP server also tells the DSX the duration of the DHCP lease. Normally, the lease is automatically maintained as long as the DSX is connected to the site LAN. However, depending on the site DHCP server set up, the DSX may be periodically provided with a new IP address. Because of this, the DHCP mode may not be the best choice when using remote programming with the System  Administrator. • DHCP with Manual IP • n this mode, the DSX gets the Subnet Mask, Router  Address, and DNS  Address from the site DHCP server but uses the IP address you manually enter.  This may be your best choice when setting up remote programming with the System  Administrator since the DSX IP address can never change.  This option does not set up a DHCP lease, so the Subnet Mask, Router  Address, and DNS Server  Address settings are applied only one time.  Always check with the site network administrator be

Ring tone

Incoming Ring Tone  to set the incoming ring tones, which are the tones a user hears when a call rings an extension. These tones are grouped into four ring tone  Ranges  (1 ~ 4), also called patterns, that consist of a combination of frequencies. (You assign a specific  Range  to trunks in Program 22-03 and to extensions in Program 15-02.) Within each range there are three frequency Types  : High, Middle and Low. (Service Code  720  allows users to choose the  Type  for their incoming calls.) Each  Type  in turn consists of two frequencies and the modulation played simultaneously to make up the tone. These frequencies are determined by their Frequency Number selected in Items 1 and 2 (see below). In this program, you assign the two  Frequency Numbers  and  Modulation  for each Type, for each of the four  Ranges. The chart below shows the default  Frequency Numbers  for each Type  in each  Range.

Override Mailbox Category

Override Mailbox Category  (Override MB Ctg) Use this option to specify the category of the mailbox where Automated Attendant calls should route when you enable Answer Schedule Override. • If the Override Mailbox is a  Subscriber Mailbox, the outside caller hears the mailbox greeting (if recorded) and can leave a message. Program 47 • If the Override Mailbox is a  Master Mailbox, the outside caller shears the recorded announcement. Depending on how the Announcement Mailbox is programmed, InMail then hangs up, reroutes the call, or provides additional dialing options. • If the Override Mailbox is a  Routing Mailbox, the outside caller hears the instruction menu and can dial any option allowed by the associated Dial Action Table.If any of the Input Data values are entered, the terminal displays the Override Mailbox Number  selection (below). Override Mailbox Number  (Override MB Num) Use this option to specify the mailbox where Automated Attendant calls should route when you enable Answer Schedule Override. The mailbox number you select in this option should match the mailbox category specified in  47-11-02 : Override Mailbox Category  above.

Rec Conv

Rec Conv Beep) Use this option to enable or disable the Conversation Record beep. If enabled, all parties on a call hear the voice prompt “Recording”, followed by a single beep when the extension user initiates Conversation Record. If disabled, the voice prompt and beep do not occur. When you disable the Conversation Record beep, the following voice prompts do not occur while InMail records the conversation: Recording (followed by a beep) That mailbox is full (if the mailbox message storage capacity is reached) You have reached the recording limit (if the recorded message is too long) Provides an additional Conversation Record beep. This beep repeats according to the setting of  Program 45-01-06 : Voice Mail Integration Options :  Record Alert Tone Interval Time (0 ~ 64800 seconds). To disable Conversation Record beep, enter 0 for this option. 1 06 07 08 09 10 Message Waiting Lamp Auto Attendant Direct to Voice Mail Forced Unscreened Transfer Auto Time Stamp 0 = No (Disabled) 1 = Yes (Enabled) 0 = No (Disabled) 1 = Yes (Enabled) 0 = No (Disabled) 1 = Yes (Enabled) 0 = No (Disabled) 1 = Yes (Enabled) System Administrator 0 = No (Disabled) 1 = Yes (Enabled) (Update MW Lamp) Use this option to enable or disable Message Waiting light at the extension associated with the Subscriber mailbox. For Subscriber Mailboxes, you should leave this option enabled. For Guest Mailboxes, you should leave this option disabled. Use this option to enable or disable Auto Attendant Direct to VM. When a subscriber enables Auto Attendant Direct to VM, an Automated Attendant caller routes directly to the mailbox, hears the greeting, and is asked to leave a message. A subscriber can also enable Auto Attendant Direct to VM while recording their mailbox greeting. (Forced UTRF) Use this option to enable or disable Automated Attendant Forced Unscreened Transfer for the Subscriber Mailbox. If enabled, each Screened Transfer (TRF) to the extension is converted to an Unscreened Transfer (UTRF). If disabled, Screened Transfers from the Automated Attendant occur normally. Use this option to enable or disable Auto Time Stamp for the Subscriber Mailbox. If enabled, after the subscriber listens to a message InMail announces the time and date the message was left. Auto Time Stamp also announces the message sender (if known). A subscriber can also enable Auto Time Stamp from their mailbox. (System Admin) Use this option to designate the Subscriber Mailbox as a System Administrator. This allows the subscriber to use the options after logging onto their mailbox.

Forced UTRF

Forced UTRF) Use this option to enable or disable Automated Attendant Forced Unscreened Transfer for the Subscriber Mailbox. If enabled, each Screened Transfer (TRF) to the extension is converted to an Unscreened Transfer (UTRF). If disabled, Screened Transfers from the Automated Attendant occur normally. 0 11 Program 47 12 13 14 15 16 17 18 19 20 21 22 23 Auto Time Stamp 0 = No (Disabled) 1 = Yes (Enabled) System Administrator 0 = No (Disabled) 1 = Yes (Enabled) Dialing Option Next Call Routing Mailbox 0 = No (Disabled) 1 = Yes (Enabled) Call Routing Mailbox Number (1 ~ 3 digits, 00 ~ 32) (00 = Undefined) No entry (Entered by pressing CLEAR) Directory List Number 0 = None 1 ~ 8 = List Number * = All Voice Prompt Language Enable Paging Paging Option Telephone User Interface Type Enable E-mail Notification E-mail Address Include Message as Attachment All Message Notification Enabled Refer to  Table 2-9 47-02-16 Default Table on page 2-407. 0 = No (Disabled) 1 = Yes (Enabled) 0 = RNA 1 = Immediately 0 = Numeric 1 = Mnemonic 0 = No 1 = Yes Up to 48 characters 0 = No 1 = Yes 0 = No 1 = Yes Use this option to enable or disable Auto Time Stamp for the Subscriber Mailbox. If enabled, after the subscriber listens to a message InMail announces the time and date the message was left. Auto Time Stamp also announces the message sender (if known). A subscriber can also enable Auto Time Stamp from their mailbox. Use this option to designate the Subscriber Mailbox as a System Administrator. This allows the subscriber to use the  SA  options after logging onto their mailbox. Dialing Option provides additional dialing options for Next Call Routing Mailbox calls (see Next Call Routing Mailbox below). If enabled, a caller who accesses the Subscriber Mailbox to leave a message can dial any of the options in the Next Call Routing Mailbox Dial Action Table. If disabled, the caller can dial only 0 (to use the Next Call Routing Mailbox 0 action). (Next CR Mbox) Use this option to assign a Next Call Routing Mailbox to the Subscriber Mailbox. This provides callers with additional dialing options while listening to a Subscriber Mailbox recorded or default greeting. The digits the caller can dial depend on the setting of the Next Call Routing Mailbox and Alternate Next Call Routing Mailbo

RNA

Notify N-Pgr Intvl) Use this option to set the minimum time (1 ~ 255 minutes) between non-pager Message Notification callouts in which the destination answers, says Hello, dials 1 to acknowledge and then enters the wrong security code. 20 11 Program 47 12 13 14 15 16 Wait Between Busy Non-Pager Callout Attempts Wait Between RNA Non-Pager Callout Attempts Number of RNA rings (V1.5 Changed) Number of Cascading Attempts  (V1.5 Changed) Send Pager Callout Until Acknowledged Name Format 1 ~ 255 minutes 1 ~ 255 minutes 1 ~ 99 rings 1 ~ 99 rings 0 = No (Disabled) 1 = Yes (Enabled) 0 = First-Last 1 = Last-First (Notify Busy Intvl) Use this option to set how long InMail waits (1 ~ 255 minutes) after it dials a busy non-pager callout destination, before retrying the callout number. (Notify RNA Intvl) Use this option to set how long InMail waits (1 ~ 255 minutes), after it dials an unanswered non-pager callout destination, before retrying the callout number. There are 3 types of unanswered non-pager callouts: • If the callout rings the destination longer than the 47-01-13: Wait for Answer NonPager Callout Attempts option. • If the destination answers, says Hello (or the system detects answer supervision) and then hangs up without dialing 1 to log onto their mailbox. This typically happens if someone unfamiliar with notification answers the callout, or if the callout is picked up by an answering machine. • If the destination answers and then hangs up without saying Hello. This typically happens if someone unfamiliar with the notification answers the callout (like the above example), or if the call is picked up by an answering machine with insufficient outgoing message volume. If a non-pager callout rings the destination longer than this interval (1 ~ 99 rings), InMail marks the call as unanswered (Ring No Answer) and hangs up. Use this option to set how many times (1 ~ 99 rings) InMail retries an incomplete Message Notification callout. This total includes unacknowledged callouts, callouts to a busy destination, and callouts to an unanswered destination. This option applies to pager and non-pager callouts. (Retry Until Ack) When this option is enabled (1), InMail continues to retry a digital pager Message Notification callout until the notification is acknowledged. If this option is disabled (0), InMail retries a digital pager Message Notification the number of times specified in  47-01-14 Number of Callout Attempts. This option does not apply to Message Notification callouts to telephone numbers. A digital pager notification is considered acknowledged when the recipient logs onto the mailbox. Specify if names are displayed in FirstLast format or Last-First.

Gain Table for ARS

Gain Table for ARS/F-Route Access  to set the gain/PAD table. If an extension dials ARS/F-Route number: • The Extension Dial Gain Table, assigned in Program 44-05, is activated. • The Extension Dial Gain Table follows Outgoing transmit and Outgoing receive settings. If the incoming call is transferred to another line using ARS/F-Route: • The Tandem Gain Table, assigned in Program 44-05, is activated. • The Tandem Gain Table follows the Incoming transmit and Incoming receive settings for incoming line, and Outgoing transmit and Outgoing receive settings for the outgoing line.

Class of service

Class of Service Options (Hotel/Motel)  to set the Hotel/Motel Class of Service (COS) options. Assign Class of Service to extensions in Program 42-02 : Hotel/Motel Telephone Setup. There are 15 Classes of Service. Refer to the following chart for a description of each COS option, its range and default setting. For additional Class of Service options, refer to Programs 20-06.

Pre-Ringing Setup to enable or disable

Pre-Ringing Setup  to enable or disable pre-ringing for trunk calls. This sets how a trunk initially rings a telephone. With pre-ringing, a burst of ringing occurs as soon as the trunk LED flashes. The call then continues ringing with the normal ring cadence cycle. Without pre-ringing, the call starts ringing only when the normal ring cadence cycle occurs. This may cause a ring delay, depending on when call detection occurs in reference to the ring cycle.

simple design

Stand-by  —  A  very  simple  design that  affects power  only  when  either  a lag/brownout  occurs  below,  or  a spike/surge occurs  above,  a  certain threshold.  When  either  occurs,  the  unit  trips  —  i.e.,  goes  into  battery mode.  This  "cleans"  the  voltage  and helps to  keep  any load  safe.  Industry  average "trip"  times  are  2–8 ms.  No  other  filtration  of  AC power  is  performed. •  Line  interactive  —  Constantly  monitors  inbound voltages,  and  uses  special  circuitry to  boost  low  voltages and clamp high  voltages  without  having to  use the batteries.  Indeed,  the  batteries  are  used  only  if  the input  voltage drops  below  acceptable levels  (typically  about  12%  below  normal),  goes  out  completely  or rises  to  dangerous  levels  (typically  about  14%  above  normal)  at  which  components  will be  damaged  if  line voltage  is  not removed.  Industry  average  transfer  time  is  1–3  ms. (If voltage  stays  within  its  normal window,  this  unit  continues to  pass  voltage,  unaltered,  from  the  wall.) •  On-line  (or  full on-line)  —  Constantly  filters the  power  and  performs  a function  known as  double conversion  (AC  to  DC  to  AC).  This  assures  that  the  load  —  in  this  case, phone  equipment  —  will receive not  only  uninterrupted,  true  sine  wave  output  but  also  the  cleanest,  steadiest  power  possible throughout any foreseeable  power  disruptions  or  voltage irregularities.  According to  industry  specs,  it  is  not  unusual for these  types  of  units  to  be  able  to  regulate  utility  power,  even  when  it  drops  to  27%  below  or  rises  to 33% above normal,  all  without  using  their  batteries. From  this  point,  UPSs  can be  further  broken  down  by  inverter  types,  which determine output.  These are: •  Square  wave. •  Modified sine  wave  (or  quasi  sine  wave). •  Sine wave.  Most  devices with  wall-mounted chargers,  such as cordless  drills  or  screwdrivers,  can  behave erratically  — sometimes  not  allowing the charge  circuit  to  engage  at  all  —  when  operating with  modified  sine  or  square wave inverters.  Small  wall-based transformer-style  power  supplies,  similar  to  those ESI  phone systems  use, can experience overheating  problems  with  modified  sine  or  square  wave  outputs,  which  occur  while  some UPSs  are operating in  battery mode.  This  overheating could  eventually  cause  damage to  the power  supplies; and,  in  time,  the  damage  could cause a  spike through the phone system  —  seriously  damaging some  of  the static-sensitive  components  inside the  casing.   While  the  true  sine wave UPS output  power  curve smoothly  increases  to  its peak,  then  smoothly   decreases  (allowing  connected  loads  and  equipment  to  operate  the  same  as  they  would  from  utility  supplied wall  power),  the  modified  sine  wave  and  square  wave  UPS  output  power curve  will shoot straight  up,  level  off at  peak  voltage and  then  drop  straight  down.  Additionally  troublesome is  that  the modified  sine  wave  sits  at zero  voltage for  a short  period  during the transition to  or  from  batteries  —  which is  the  main  difference between it  and the  square  wave  output  of  some  UPS.  Please  note  that  this  short  interval  during  which the modified  sine  wave  UPS sits  at  zero  voltage  can  directly  affect  the transfer  time  of  the UPS  and could, theoretically,  be  enough  to  cause  the  phone  equipment  to  reset  or  even  “freeze.” Though  it  is  hard  to  predict exactly  when  different  ESI  systems  will have  problems  with  modified  sine  wave  or square waveform  UPSs (meaning  during  a  power  failure  event  or  the recovery  from  one),  it’s  fair  to  assume that  a  problem  will eventually  arise  from  the  use  of  such  UPSs.  Therefore,  ESI  recommends that  only true sine  wave  output  UPSs  provide  backup  power to  our phone  systems  and  equipment.
