CONFIGURATION GUIDELINES
Remove the blank Port Assignment Record forms (Figures 4 and 5) and duplicate as many times
as necessary to have enough pages for each type cabinet and associated circuit packs to be
assigned in the System. A blank Port Assignment Record for eight ports (Figure 4) is required for
all circuit packs that contain up to eight ports. Each 8-port record provides assignment space for
four slots on a cabinet. A blank Port Assignment Record for 24 ports (Figure 5) is required for
each slot that will house circuit packs that contain more than eight ports, for example, the TN767
DS1 Interface or TN746 Analog Line circuit pack.
Obtain sets of blank records for all Control, Expansion and Port cabinets to be used, then com-
plete the following:
1. With a set of records for a single-carrier cabinet-following the “CARRIER” entry at the
top of the form, enter the applicable cabinet ID as follows:
● Enter 1 A for the Control Cabinet (J58890L-1 ) without the Duplication Option.
● Enter 1 B for the Control Cabinet (J58890M-1 ) with the Duplication Option.
● Enter 2A (EPN 1) or 3A (EPN 2) for the Expansion Control Cabinet (J58890N-1).
● Assign a letter (B, C, or D) to all records for each Port Cabinet (J58890H 1). Use
the letter as noted on Figure 6, 7, or 8 for the Port Cabinet location in a single
port cabinet configuration.
2. Following the “CABINET” entry at the top of the record, enter the applicable type cabinet
as either PPN, EPN 1, or EPN 2.
3. Repeat the above steps and complete a set of records for each System cabinet.
4. Assign port circuit pack slot numbers on the sets of records as follows (refer to Table D
for circuit pack port slot availability and associated notes):
● For Control Cabinet 1A, begin with slot number 1 and number through 10.
● For Control Cabinet 1 B, begin with slot number 1 and number through 10.
● For the Expansion Control Cabinet 2A or 3A, begin with slot 1 and number
through 17.
● All Port Cabinets (B, C, or D) slots should be numbered 1 through 18.
