Description
3
Beginning with Release 3.0, the system supports Caller ID. This feature is part of
local telephone companies’ Custom Local Access Signaling Service (CLASS). It
provides a user with calling party number information from the central office (CO)
when a call rings on a loop-start line connected to an 800 GS/LS-ID module. This
information appears on MLX display telephones, much like the Primary Rate
Interface (PRI) Automatic Number Identification (ANI).
NOTE:
Calling number identification is not available in all areas or jurisdictions.
Check with your local telephone company. The availability of caller
identification information may also be limited by the local-serving (caller’s)
jurisdiction, availability, or central office equipment.
800 GS/LS-ID Circuit Module
3
The 800 GS/LS-ID circuit module provides eight analog loop-start or ground-start
line/trunk jacks, with each port capable of processing Caller ID information (over
loop-start lines only). It also provides two touch-tone receivers (TTRs) and can
have updated firmware downloaded to it through a PCMCIA card inserted in the
processor module.
The module may be programmed through the MLX-20L or through the PC-based
System Programming and Maintenance (SPM) interface. It is stored with other
system information about the PCMCIA memory card. Beginning with Releases
following 3.0, this module is upgradable through the memory card. (For
