7-112ADMINISTRATION OPTIONS AND REQUIREMENTS — SYSTEM 75

Trunk Group/Trunk Group Members

For System 75 R1V2 and R1V3, there are three applications for a DS1 (tie and DMI); refer to table 7-6,Equipment Parameters and Permitted Translation Encodes.

The DS1 tie trunks are defined by using Page 1 of the TRUNK GROUP screen; this is the same as for analog tie trunk groups. Trunk members are added to the GROUP MEMBER ASSIGNMENTS screen (pages 2 through 5). This series of screens administers many of the same parameters as procedures 100 and 101 do for System 85. Figure 7-57, Trunk Group Screen, depicts this procedure.

Figure 7-57.Trunk Group Screen, Page 1

Most fields require no unusual entries for DS1 tie trunk applications. Only those that may require special attention are mentioned.

Comm Type The default is voice with avd and data being the alternate selections.

NOTE: Trunk groups that are administered avd require that the DS1 also be administered for common-channel signaling (24th). Furthermore, if avd is translated; then Bit Rate, Synchronization, and Duplex fields are displayed. These three fields enable the trunk group to function with a modem pool. A Data Originate code is required to start a modem pool call. The avd option is equivalent to translating System 85 procedure 101, field 17, with a 1.
