Operating parameters 419
M1A represents the current Bell MF signaling mode. M2B represents the
modified Bell MF signaling mode.
Automatic Number Identification/Central Automatic Message
Accounting
CAMA routes using Bell MF signaling Mode B outpulse KP + 0 + ..., +
START and allow 00- and 00+ calls. 00- and 00+ calls are denied for routes
using a different signaling mode.
Controlled Class of Service Allowed (CCSA)
CCSA routes do not support ANI/CAMA.
Route Selection (RS)-Automatic Number Identification
Route Selection for ANI does not support 00- and 00+ dialing. Calls made
using 00+ or 00- are treated as 0+ calls. The RS-ANI Data Block determines
the 0+ call routing.
Operating parameters
Automatic Number Identification (ANI)/Digital Trunk Interface (DTI) supports
CAMA trunks. CCSA-ANI trunks are not supported.
ANI/CAMA operates on a route basis and applies to CAMA routes using
the Bell MF signaling method only.
All route members must have a Multifrequency Route (MFR) Class of
Service (CLS).
ANI/CAMA is not supported over Dial Pulse trunks. When activating this
feature, do not use mixed trunk members.
If 1 or 0 is not dialed following the Trunk Access Code, the system intercepts
all outgoing calls over CAMA trunks. This restriction does not apply to
outgoing calls over CCSA-ANI trunks.
For E&M or DX signaling, use the QPC71 E&M/DX/Paging trunk circuit
card. This card does not have to be modified for ANI. For a complete
description of this trunk circuit card.
For loop signaling, the QPC72 loop signaling trunk circuit card is used.
The two trunk cards mentioned above provide compatibility with the
signaling and supervision requirements of CAMA trunks. They also provide
a path for the eventual analog transmission of the MF tones and for speech
transmission.
