Installation, Section 300 Trunks and Lines Issue 2 August 16,1993 l The Tl trunk card must be installed in the “EC/-IRK” slot. l The installer must provide a Channel Service Unit (CSU) that complies with FCC Part 15 and Part 6X. The CSU is installed between the DBS and the public network. The CSU provides alarm diagnostic, and monitoring functions, as well as network protection. The CSU must be compatible with the framing format (SF or ESF) that is provided by the public network. Maximums l One Tl card can be installed per cabinet. l The number of Tl cards that can be installed in double-cabinet systems depends on the sizes of the connected systems. Table 4- 12 on page 4- 13 shows Tl maximums for double-cabinet systems. Note: The DBS 72 + DBS 40 combination does not support Tl. Table 4-8. Tl slot usage for two-cabinet systems l Fractional TI can be used when fewer than 24 Tl trunks are needed. Fractional Tl allows you to use only a portion of the 24 channels provided on the Tl card. l Though each Tl Interface provides 24 trunk channels, Tl trunks do not increase the overall trunk capacity of the DBS. Each Tl channel subtracts from the total number of analog trunks that can be installed. Furthermore, the number of analog trunks that can be used are always decremented in quantities of 8. ,- / For instance, if you’re installing a Tl in a DBS 96 and you only want to use 12 Tl channels, the logical number of analog trunks that would be available is20(32- 12=20). 4-10
Installation. Section 300 Issue 2 Trunks and Lines August 1.6, 1993 However. because the number of analog trunks must be decremented in quantities of X. the actual number of analog trunks that can be used is 16: (32 total trunks - 16 (two 8-trunk increments) = 16.1 Tables 4-Y through 4-l 1 show the possible combinations of analog and digital trunks assignments based on system size. The trunk numbering shown in these tables is determined by backplane trunk port assignments. Therefore, the numbering cannot be changed. Note: Analog trunks are numbered beginning with “l.“Tl trunk channels are numbered beginning with the highest trunk channel used. Trunk Assignments for Single-Cabinet Systems l Programming is not required to associate trunk ports with slot locations. However, you must use programming to specify that a combination of Tl and analog trunks are installed, and you must also specify how many Tl channels are used. Table 4-9.

Installation, Section 300 Issue 2 Trunks and Lines August 16, 1993 Trunk Assignments for Double-Cabinet Systems l When Tl is used in a double-cabinet system, the number of Tl channels that can be assigned in each cabinet depends on the master/slave designation. The following table shows the maximum number of Tl channels that can be assigned in two-cabinet systems. Table 4-12. Maximum Tl assignments for 1 System Size 1 DBS4O+DBS40 1 DBS 72 + DBS 72 DBS 96 + DBS 72 DBS 96 + DBS 96 two-cabinet systems Master 1 Slave 8 analog trunks 16 Tl trunks 16 analog; trunks 24 Tl trunks 24 Tl trunks 8 analog trunks 24 Tl trunks 8 analog trunks l Two-cabinet systems use the same trunk numbering scheme as single-cabinet systems: analog trunks are numbered from “1” upward; Tl trunk channels are numbered downward from the highest channel used. Tables 4- 13 through 4-17 show trunk numbering for two-cabinet systems using the maximum number of Tl channels. Table 4-13.

The procedure that you should use depends on the type of system you have and the number of Tls you are installing. If you’re installing . . . Use this procedure...

These instructions also apply when a Tl is installed in only the master cabinet of a two cabinet system. Lf only one Tl is installed in a two-cabinet system, it must be installed in the ( cabinet specified in Table 4-8 on page 4- 10. Note: For systems consisting of a DBS 72 connected to a DBS 40, the Tl Interface cannot be used. 1. Before beginning Tl installation. perform the “New Function Reset” command (FFI 8# I# (0- l)#). This command must be issued before the Tl can be installed properly. 4-13
