AT&T DS1/DMi/ISDN-PRI manual Procedure 014 Word 2 Bccos Data Options

7-78ADMINISTRATION OPTIONS AND REQUIREMENTS — GENERIC 2

Fields 4-13The translation parameters administered for fields 4 through 13 determine what actions the switch will take for the BCCOS specified in field 1. Regarding Generic 2, it is important to remember that the administration (of the BCCOS) determines when a modem pool member is added and not the particular trunk type. By administering the BCCOS on an AAR/ARS preference basis allows a single trunk group to support both circuit switched and modem pooled calls. Field encodes and their descriptions are:

0Circuit switch the call

1Insert a mode 2 modem pool

2Block the call

Fields 14 through 16 are the default capabilities assumed by the switch for an originating facility (on this switch) that does not have a BCCOS IE (non-ISDN). The switch assumes these default capabilities are acceptable to the originating facility when it tries to connect the originating facility to the terminating facility. These default capabilities are not the predefineed BCCOSs that default through administration.

Field 14	Assigns a packet switched (1) or a circuit switched (0) call transport mode
Field 15	Assigns a clear (1) or a restricted (0) channel type. This relates to calls outgoing
	from an endpoint, except for DMI modes 0 or 3.
Field 16	Used for an outgoing call BC IE (except for BRI modes). Field encodes and their
	descriptions are:
	0	Voice
	1	Mode 1
	2	Mode 2
	3 Mode 3
	4 Mode 0
	5 Voice grade data
	6	Unknown digital
	7	Unknown analog
	8	Mode 3/2
	9	X.25

Procedure 014 Word 2: BCCOS Data Options

This procedure is used to define the data capabilities for the modem pools. The data rates selected are dependent on local requirements and the particular type of analog modem used. Figure 7-37,Procedure 014 Word 2: BCCOS Data Options, depicts this procedure.
