Downloading Terminal Parameters
The following information explains how maintenance software interacts with
terminal parameter downloading.
The software can interact with the following terminal types:
a. 84xx multibutton digital voice terminals (8403D01A, 8410B, 8410D02A,
8434D01A) with optional expansion module.
b. 603A1 and 603D1 Callmaster terminals for telemarketing applications.
c. 302B1 and 302C1 attendant console.
Circuit Packs:
1. 8400x, 302B1 Terminals
a. TN754 (4-wire, mu-law)
b. TN413 (4-wire, A-law)
c. TN754B (4-wire, A-law/mu-law selectable)
d. TN2177 (2-wire, 16-port, A-law/mu-law selectable)
e. TN2181 (2-wire, 16-port, A-law/mu-law selectable)
f. TN2224 (2-wire, 24-port, A-law/mu-law selectable)
2. 603A1/D1 Terminals
a. TN754 (4-wire, mu-law),
b. TN413 (4-wire, A-law)
c. TN754B (4-wire, A-law/mu-law selectable)

The port, and thus the station, have been removed from service.
Busyout puts the port in the out-of-service state.
The port on the circuit pack has been put into service, but the voice
terminal has not yet established signaling communications with the
port.
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.
Minimum usable vintage for 8410D and 8434D terminals - V11
