INSTALLATION
Initialize System
Instructions for initializing the system (based on the completed
implementation forms) are provided in the Administration Manual
(555-540-500).
Note: Before trunks using DS1 Signaling are administered, all link
level parameters such as signaling and framing and all link
level alarms must be cleared. If this is not possible, PBXs at
each end will not work.
If this condition exists, clear a
maintenance busy condition that exists at each end.
