Administering Analog Caller ID (Switch)
The TN2793B and TN793B analog line circuit packs can be administered to 
deliver Incoming Calling Line Identification (ICLID) data to stand-alone analog 
Caller ID display units or analog telephones with built-in Caller ID display units. 
For this feature to work, the serving central office (CO) must support delivery of 
Caller ID information over the trunks that are serving the switch. To administer this 
feature, do the following:
Administer the Caller ID system options.
Administer stations with Caller ID options.
Administering Caller ID
Use the change system-parameters features command to select the Caller ID 
protocol that matches the protocol used by the Caller ID units or telephones, and 
to enable display of Caller ID information for room-to-room calls. These options 
are set on a system-wide basis. Administer the following options:
Protocol for Caller ID Analog Terminals
 — The available 
protocols include:
— Bellcore (default) — US protocol (Bellcore transmission protocol 
with 212 modem protocol)
— V23-Bell — Bahrain protocol (Bellcore transmission protocol with 
V.23 modem protocol).
