If you are adding a DID or tie trunk, evaluate the cabinet unit power
load using the procedures under Evaluate Cabinet Unit Power Load
in this appendix.
Check to see that the trunk has been connected to an RJ21X (for a
DID trunk) or RJ2GX (for a tie trunk) network interface by the
telephone company.
If the trunk is connected to an existing network interface, determine
the correct wires on the connecting cable. Cut them down to the
correct position on the TAE connecting block, following the
procedures under “Install Cross-Connect Equipment” in Section 2.
If the trunk is connected to a new network interface, connect it to the
TAE followingthe procedures under “Install Cross-Connect
Equipment” in Section 2.Install the correct CP as described under
“Add Circuit Pack” in this appendix. Connect a plug from the
splitter cable to the connector of the above CP at the back side of
the cabinet.
Install secondary wiring protectors. (See Table 2-B.)
Follow standard procedures for translating the trunk port using the
SAT.

discard (R1 only). Remove ZTN85 Service CP from slot 3 (R1 only) or
slot 2 (R2 only) and replace with ZTN131 Service CP. (Put in slot 2.) If
ZTN85 is not replaced, move ZTN85 to slot 2.
Power up the system-Cabinet 1 last.
Cold start the system. Refer to “Cold Start the System in Section 2.
Restore the translations from the backup tape. Refer to “Using the DTU”
in Section 4.
Install any new port circuit packs.
Caution:Do not Install new port circuit packs until after
backup tape has been restored.
Note:
The system must be idle to perform the following step.
From R1 to R3 one: The new slot location (slot 2) of the ZTN131 CP
must be translated as follows:
lSelect Menu 1.
lRemove port 10301 by entering Port=10301, Action=1, and
Data=0.
lAssign port 10201 by entering Port=10201, Action=1,
Data=1102.
Enter new or changed transations as needed so that the customer
can use the new R3 capablities (Note). Refer to the Administration
Manual for R3V1 (555-540-500) for these procedures.
Note:
If you are replacing a direct trunk console with a switched
loop console, you must remove the direct trunk console
translations and enter translations for the switched loop
console. Also, the switched loop console does not have a
NIGHT SERVICE button by default; therefore, you must
administer one, if the Night Service feature is required (note
the Night Service Access code before switching the
consoles). Set trunk priority to ring-in on SLAC Menu 1,
Action=11, Data=1 through 7.

(Contd)
Administering the TN746B with Basic Administration
Plug the TN746B into an unadministered carrier/slot location and warm start the
System 25.
Note: The TN746B circuit pack is not interchangeable with either the
ZTN78 or TN742 circuit packs from an administration point of
view. Therefore, if a TN746B circuit pack is to be plugged into a
slot formerly populated by a TN742 or ZTN78, all of the latter
translations must be removed before the System 25 is warm
started. (The TN746B must be plugged into a slot before warm
starting the system and/or administering the circuit pack.)
At this point, the rules for administering this circuit pack follows the normal
ZTN78 and TN742 circuit pack procedures, with one exception. If it is necessary
to administer the TN746B circuit pack to an extended station, the ACTION 10
(Make this an extended station) item under PORT administration in the Main
Menu will not work. Also, do not utilize the ACTION 36 (Set gain) DATA 1 (Gain
= 3db) option to make the station extended. This is accomplished by utilizing the
ACTION 35 (Set Hybrid Balance), DATA O (Resistor/Capacitor Term.) option.
Administering the TN762B with Basic Administration
All TN762B administrative procedures should follow the same administrative
procedures as a ZTN79 circuit pack.
