6.4.1 V.24 W
IRELINE
PDR8000 is equipped with a V.24 wireline interface allowing it to optionally be connected to
other Futurecom & Motorola equipment supporting Motorola's AIS protocol over V.24.
Connections may be to another PDR8000 or Motorola station to support an RT/RT configuration
(see 3.2), or to a system infrastructure including consoles, data interface, and/or a voting
comparator (see 3.1, 3.4). Depending on the distance between the devices being connected,
external V.24 MODEMs (not provided) may be required. Installations requiring a link distance of
50 feet or less generally do not require MODEMs.
Futurecom has tested several MODEMs with the PDR8000 product:
•
Raymar-Telenetics V.3600 SA Modems
•
Paradyne 325
•
Motorola UDS V.3225
•
Motorola Codex 3260 Fast Data Modem
Visual indications reflecting activity on the V.24 wireline interface are visible via the PDR8000's
status LEDs (see 6.10).
The V.24 wireline interface is optional functionality of the PDR8000. Deployment Profiles
created that utilize the V.24 interface are allowed to contain only digital/P25 channels.
Deployment Profiles that do not use the V.24 interface (i.e. Deployment Profiles intended for
use as a standalone repeater) can contain a mixture of P25, analog, and mixed-mode channels.

ITE UBSITE
When there are many pieces of equipment connected via V.24 interfaces, it is allowable for
common infrastructure signalling information/messages to be delivered to many infrastructure
endpoints, even when it is desired for only some of the endpoints to act on the message
(commands, data, or audio). In order to allow for selective addressing/processing of the
infrastructure signalling, an intended target address (TEI: Terminal Endpoint Identifier) is
identified in the messaging. TEI values are 6 bits long, and are examined by each receiving
entity to determine whether the message should be processed by that entity. All 6-bit values of
TEI are valid. Most values target a specific device, but two values have special meaning:
TEI = %000000 = $00 (Null Address)
TEI = %111111 = $3F (Broadcast Address)
