Caller ID generation with the STA protocol

A call originated on an AG 2000 subscriber loop board that is running the STA protocol can automatically transmit an FSK caller ID sequence during the ring cycle.

The adsix.m54 DSP file (FSK transmitter) must be loaded on the board.

The following table describes the values for the lower 3 bits of NCC.X.ADI_STA.cidsupport:

Value

Description

0x00

Disable caller ID generation (default).

0x01

Generate Bellcore data format caller ID.

0x03

Generate ETSI data format caller ID.


Bits 4 and 5 control when the caller ID is generated. The following table describes the values for bit 4 and bit 5:

Value

Description

0x00

First ring is normal full cycle, caller ID follows.

0x10

First ring is abbreviated single ring, caller ID follows.

0x20

Caller ID alerting tone is transmitted, followed by caller ID, followed by normal full length ring cycles.


The information that is transmitted comes from nccPlaceCall parameters and extended arguments in CAS_PLACECALL_EXT. Parameters set to 0 will not be transmitted.
