AT&T DS1/DMi/ISDN-PRI manual Insert, Per Call, Sid/Ani, Case

7-136	ADMINISTRATION OPTIONS AND REQUIREMENTS — GENERIC 1
Insert	The digits inserted before the Called Party Number IE. This specifies the digits
	prepended to the front of the remaining digits after any (optional) digit deletion has
	been performed. The resultant number formed from digit deletion/insertion is used
	to route the call, providing that night service is not in effect. Field encodes and
	their descriptions are:
	●	A series of numbers, which may consists of from 1 to 16 digits.
	●	NO entry, leave the field blank. This will suffice for the case where no digits are
		to be inserted.
Per Call	Specifies if and how to request SID or ANI for this particular type of
SID/ANI	Service/Feature. Field encodes and their descriptions are:

●No entry, leave the field blank (default). Specifies that the switch will not request either SID or ANI for any of these types of calls after call delivery. Use no entry when the network is provisioned to always send SID/ANI with call setup.

●ANI-only

●ANI-pref — but will accept SID

●SID-only

●SID-pref — but will accept ANI

●None — same as blank

Night Serv Permits the administration of a particular night service extension for each row in the table. This entry will override the night service administered for the whole trunk group (on page 1 of the TRUNK GROUP screen). Field encodes and their descriptions are:

●An extension number

●The attendant

●No entry, leave the field blank (default). This will not override night service for the whole trunk group.

The TRUNK FEATURES screen (Page 2 of 11) may have more than one entry for the same Service/Feature. Frequently, multiple entries (per Service/Feature) are used to provide multiple call routes for that Service/Feature. The route selected will be dependent on the received digits and specific administration details of the digit manipulation fields. If an incoming call matches more than one entry, then the most restrictive entry is selected. (This is why it is not CBC specific.)

The following case examples show this point and should clarify how the incoming call handling software functions in this scenario.

Case 1

●Service/Feature field is specified (for example, mega800).

●Called Len field is specified with a requirement of N digits (for example, N = 5).
