Central Office Calls for NEC SL1100

Central Office Calls, Placing
The system provides flexibility in the way each extension user can place outgoing trunk calls. This lets you customize the call placing options to meet site requirements and each individual’s needs. To place a call the user can:
•Press Line Keys
•Press a Trunk Group key
•Press a Trunk Group Routing (dial 9) key
•Dial a code for a specific trunk (#9 + the trunk number)
•Dial a code for a Trunk Group (704 + group number)
•Dial a code for Trunk Group Routing or ARS (9)
•Dial an Alternate Trunk Route Access Code (which you must define)
•Press or Use a Speed Dial bin
There are 84 available trunks. Trunk Port Disable
The system provides a service code (default: 645) which can be used by an extension user to block a trunk for outgoing calls. The user which busied out the trunk still has access to it. All other users are blocked from seizing it to place an outgoing call. The trunk, however, can still be answered by any users programmed with the trunk access.
Sidetone Volume Setup
Allows the system programming for the Multiline Terminal side tone volume. There are two levels, based on whether the connected trunk is a digital trunk or analog trunk.
•If the trunk name seize display is enabled in programming, the Call Timer starts automatically after the user places a trunk call. Disabling the trunk name seize display also disables the Call Timer.
•The system can automatically select the correct type of line to use based on the number dialed and the time.
•With Automatic Handsfree, an extension user can press a line key to place a trunk call without lifting the handset or pressing Speaker key. Users without Automatic Handsfree can preselect a line key before lifting the handset or pressing Speaker key.
•Long Conversation Cutoff can disconnect incoming and outgoing CO calls after a set time period. Using the Warning Tone for Long Conversation feature allows users on outgoing calls to hear a warning tone prior to the call disconnecting.
•An extension Toll Class of Service may prevent them from dialing certain numbers.
•Dialing 9 or any other trunk access code after dialing an extension results in termination of the intercom call and a trunk is seized.
•Setting PRG 14-02-11 to On may cause a slight delay in dial tone while loop current is returned.
•When Account Codes are enabled, the user must press the * three times before the * character is passed to the Telco. The system recognizes the initial * as the beginning of an Account Code entry, the second * as the end of an Account Code entry, and the third * will be passed to Telco.
•To adjust for proper audio quality, refer to PRG 81-07 and PRG 81-17.
