Canadian Limitations Notice
Notice: The ringer equivalence number (REN) assigned to each terminal device provides an indication of
the maximum number of terminals allowed to be connected to a telephone interface. The termination of a
interface may consist of any combination of devices subject only to the requirement that the sum of the
ringer equivalence numbers of all the devices does not exceed 5.
Notice: The Industry Canada label identifies certificated equipment. This certification means that the
equipment meets certain telecommunications network protective, operational and safety requirements.
The Industry Canada does not guarantee the equipment will operate to the user’s satisfaction.
Before installing this equipment, users should ensure that it is permissible to be connected to the facilities
of the local telecommunications company. The equipment must also be installed using an acceptable
method of connection. The customer should be aware that compliance with the above conditions may not
prevent degradation of service in some situations.
Repairs to certified equipment should be made by an authorized Canadian maintenance facility designated
by the supplier. Any repairs or alterations made by the user to this equipment, or equipment
malfunctions, may give the telecommunications company cause to request the user to disconnect the
equipment.
Users should ensure for their own protection that the electrical ground connections of the power utility,
telephone lines and internal metallic water pipe system, if present, are connected together. This precaution
may be particularly important in rural areas.
Caution: Users should not attempt to make such connections themselves, but should contact the
appropriate electric inspection authority, or electrician, as appropriate.
This digital apparatus does not exceed the Class B limits for radio noise emissions from digital apparatus
set out in the Radio Interference Regulation of the Canadian Department of Communications.
Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les limites applicables aux
appareils numériques de la classe B prescrites dans le Règlement sur le brouillage radioélectrique édicté
par le ministère des Communications du Canada.

PRI Card User Guide

Introduction
The Multi-Tech PRI Card (MTPRI-HD23B for T1 or MTPRI-HD30B for E1) is a telecommunications
interface card that provides CommPlete interconnectivity to Primary Rate ISDN (PRI) public switched
telecommunications networks. The MTPRI-HD23 provides 23 B channels that provide 23 user sessions.
The MTPRI-HD30 provides 30 B channels for 30 user sessions. The PRI card directly connects a
CommPlete to a T1 or E1 circuit without the need for an external T1 channel bank or T1 channel service
unit (CSU).
The PRI card operates as an ISDN PRI card, or as an E1 or T1 card for long-haul or short-haul applications,
using 22 AWG (0.63 mm) twisted-pair wires at up to 6000 feet (0-2 km).
This manual provides information used to install, test and troubleshoot your Multi-Tech PRI card.
Product Description
The PRI card has one RJ48C connector for a LEC line connection and 10 status LEDs. It provides
intelligent support for the ISDN B and D circuits, performing all of the call setup, management, and tear-
down functions on-board. The PRI card can establish and manage separate B channel connections at 64K
bps, or it can aggregate two or more B channels for an Nx64K bps logical connection. The PRI card offers a
variety of user-definable connection modes, allowing either static or dynamic bandwidth-on-demand
operation. It performs all call management as well as full-duplex DMA processing on each channelized
data stream. Logical channel protocols are configurable for PPP, or Multilink PPP link-level protocols, or
raw (unframed) data mode.
The 16-bit interface ensures maximum performance for the most demanding data-intensive applications.
In addition, 8-bit transfers are also supported. There are no restrictions imposed on alignment during
data transfers. The on-board firmware resides in an 8 bit wide 512K byte Flash ROM.
Features
The PRI card provides the following features:
•Extensive selection of Extended mode and Expanded mode memory addressing
•ISDN BRI
•supports PPP and Multilink PPP (MLPPP) Link Level Protocols
•extensive statistics reporting (link level and call management)
•extensive status LED monitoring of Faults, LEC circuit, and host interface activity
•support of PRI ISDN, Q.921, Q.931, and NI-2 compliant LEC circuits
•support of AT&T, MCI (and other) Multi-Rate Bearer services
•compatible with AT&T 4ESS and 5ESS, NT DMS-100 and DMS-250 switches
•multiple simultaneous remote connections at N x 64K bps bandwidth on demand
Status LEDs
The PRI card contains 10 status LEDs on the front panel. The front panel is shown in Figure 1 and each
LED is described in the following listing.
