Service States
Digital line maintenance interacts with digital line circuit pack (DIG-BD), or with digital line media
module (MG-DCP) maintenance. The health of the digital-line circuit pack or media module can
affect the results of DIG-LINE testing. Keep this in mind when investigating digital-line
problems.
It is sometimes important to know the service state of a station. These service states apply to
digital-line stations:
Downloading Terminal Parameters
This section explains how maintenance software interacts with terminal parameter
downloading.
For Systems Supporting Circuit Packs
Terminal Types:
Software can interact with the following terminal types:
● 84xx multi button digital voice terminals (8403D01A, 8410B, 8410D02A, 8434D01A) with
optional expansion module.
● 603A1 and 603D1 Callmaster terminals for telemarketing applications.
● 302B1 and 302C1 attendant console.
Out-of-Service state The port, and thus the station, have been removed from service.
Busyout puts the port in the out-of-service state.
Ready-for-Service state The port on the circuit pack or media module has been put into
service, but the voice terminal has not yet established signaling
communications with the port.
In-Service state The voice terminal has established signaling communications with
the port, and the system is ready to process calls to and from that
station. A terminal in the ready-for-service state will progress to the
in-service state if it is functioning normally. It can also be forced
into the in-service state by going off-hook.
