	Figure 7-30.Procedure 262 Word 2: ISDN-PRI D-Channel Backup (Generic 2)
Field 1	Identifies a particular D-Channel group number. The range of encodes is 1 through
	255.

NOTE: ISDN trunks are assigned to a specific equipment location in procedure

116.Procedure 116 is also used to assign ISDN-PRI circuits to the D-Channel group numbers.

Fields 2-5Assigns a particular circuit pack as providing the PRIMARY D-Channel for the identified D-Channel Group Number. Table 7-8,Codeset Differences, depicts the permitted equipment ranges.

NOTE: The ISDN-PRI facility (slot) that is translated as the primary must have also been translated for (23B + 1D) signaling, procedure 260, field 7, must use encode (0).

Fields 6-9Assigns a particular circuit pack as providing the BACKUP D-Channel (which is optional) for the identified D-Channel Group Number. Table 7-8,Codeset Differences, depicts the permitted equipment ranges.

A prime objective for the design of each D-channel group is to have members from two or more modules. By accommodating this objective, it is highly recommended that the Backup D-Channel equipment location be a different module from that selected as the Primary D-Channel. The ISDN-PRI facility (slot) that is translated

as the backup must be translated for (23B + 1D) signaling, procedure 260, field 7, must have encode (0).
