Administering the TN746B with Basic Administration
Plug the TN746B into an unadministered carrier/slot location and warm start the
S y s t e m 2 5 .
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.
