Usage
7500
Assigns a 7500 Data Module. The 7500 data module supports automatic
TEI, B-channel, maintenance and management messaging, and SPID
initialization capabilities. BRI endpoints, both voice and/or data, are
assigned to either the ISDN-BRI - 4-wire S/T-NT Interface circuit pack
or the ISDN-BRI - 2-wire U circuit pack. Each can support up to 12
ports. Since BRI provides multipoint capability, more than one ISDN
endpoint (voice or data) can be administered on one port. For BRI,
multipoint administration allows for telephones having SPID
initialization capabilities, and can only be allowed if no endpoint
administered on the same port is a fixed tie endpoint and no station on
the same port has B-channel data capability. Currently, multipoint is
restricted to 2 endpoints per port.
announcement
Assigns an announcement data module. The announcement data module
is built-in to the integrated announcement circuit pack and is
administered using the Announcement Data Module screen. This data
module (in conjunction with an administered Netcon Data Module in
DEFINITY SI configurations) allows the system to save and restore the
recorded announcements file between the announcement circuit pack
and the system memory.
data-line
Assigns a Data Line Data Module. The Data Line Data Module
(DLDM) screen assigns ports on the Data Line circuit pack (DLC) that
allows EIA 232C devices to connect to the system. The DLC, with a
companion Asynchronous Data Unit (ADU), provides a less expensive
data interface to the system than other asynchronous DCP data modules.
The DLC supports asynchronous transmissions at speeds of Low and
300, 1200, 2400, 4800, 9600, and 19200 bps over 2-pair (full-duplex)
lines. These lines can have different lengths, depending on the
transmission speed and wire gauge.
The DLC has 8 ports. The connection from the port to the EIA device is
direct, meaning that no multiplexing is involved. A single port of the
DLC is equivalent in functionality to a data module and a digital line
port. The DLC appears as a data module to the Digital Terminal
Equipment (DTE) and as a digital line port to the server running Avaya
Communication Manager.
The DLC connects the following EIA 232C equipment to the system:
•
Printers
•
Non-Intelligent Data Terminals
•
Intelligent Terminals, Personal Computers (PCs)
•
Host Computers
•
Information Systems Network (ISN), RS-232C Local Area
Networks (LANs), or other data switches.
