Data Port Module for 12-Line and 24-Line Analog Endpoints
To change the bit rate of your PCDPM:
1. While on-hook, enter the Program Bit Rate feature code (393). If the port is not config-
ured for a DSS/BLF unit, the display shows ENTER BIT RATE. (
If it is configured for
DSS/BLF, the display shows CANNOT PROGRAM BIT RATE.)
2.
Enter a valid rate (300, 600, 1200, 2400, or 4800). Model 8560 and Executive Display
users can press the appropriate menu button in the display. The display shows BIT
RATE UPDATED. (
If the entered baud rate was already in effect, it shows NO
UPDATE PERFORMED.)
Data Port Module for 12-Line and 24-Line Analog Endpoints
All GMX 24-line and IMX 12- and 24-line analog endpoints may be equipped with optional
Data Port Modules (refer to REPLACEMENT PARTS for the part number). The module con-
tains a four-conductor, RJ11 modular jack that can be used to connect
either a data device
(such as a personal computer equipped with a modem) or a loud ringing adapter (LRA) and an
external signaling device (such as a loud bell, horn, flashing light, etc.) to the endpoint. Refer
to
page 92 for operating instructions.
Optional Data Devices
A customer-provided, modem-equipped data device (such as a data terminal or a personal com-
puter) may be attached to an Inter-Tel endpoint that has an optional data port module installed.
Model 8560, Model 8520, Executive Display, Professional Display, Standard Display, and
Associate Display endpoint users can adjust the bit rate (bps) of the PCDPM connected to the
endpoint. The rate can be set to 300, 600, 1200, 2400, or 4800 (1200, 2400, or 4800 on a sys-
tem serial port). To adjust the bit rate of your PCDPM, refer to the instructions on
page 91 .
The circuit with the data port module can be programmed to be associated with one or more
other endpoints. The associated endpoint(s) should have a
button that will show the
status of the data device and will allow easy transfers between the endpoint and the data
device.
Data calls are transmitted over the data port voice path. This leaves the attached endpoint’s
voice path available for normal endpoint operation. However, receiving off-hook voice
announce (OHVA) calls at an Model 8560, Model 8520, Executive Display, Professional Dis-
play, Standard Display, or Associate Display endpoint attached to an MDPM is not possible
during a data call since the data call is using the secondary voice path.
Calls can be transferred back and forth between an associated endpoint’s primary voice path
and data port as often as needed provided that the data port is on-hook at the time of the trans-
fer attempt. For example, a call can be placed using the data device, then transferred to the
endpoint’s primary voice path to announce the call, and then transferred back to the data device
so that it can communicate with the called device. (Note that transferring to the endpoint’s pri-
mary voice path disconnects the data device from the call. During that time, the call cost dis-
play for the data call is shown on the endpoint.)
Operation of the data device begins with the initiation of a call in one of four ways:
•
The user may initiate a call using the endpoint, while on- or off-hook, and then transfer
it to the data device.
•
The user may lift the handset to answer a ringing call and then transfer it to the data
device.
•
The user may initiate a call using the data device, without touching the endpoint.
•
The data device may receive a call directly, without using the endpoint.
