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 teardown 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.

Introduction
This chapter provides the processes and procedures to help solve PRI card problems. The steps are generally presented in the recommended chronological order.
General Troubleshooting Process
At the first indication of a problem, perform the steps below. The recovery options are listed in the recommended chronological order (from simplest and most likely to most complex and least likely cause).
1. Verify that your site meets the specifications (Environmental Requirements, Physical
Characteristics, Power Requirements, On-Board Hardware Resources, Host Interface, CSU/T1
LEC Interface Standards, and Primary Rate ISDN Standards) earlier in this manual.
2. Verify proper hardware installation procedure (earlier in this manual).
3. Check the LEC cabling (earlier in this manual).
4. Check the Startup Self Test, refer to the Startup Self Test LED Patterns in the following section.
5. Check the Run Time Test, refer to the Run Time LED Status Indicators in the following section .
6. Re-try the failed operation.
7. Call your LEC representative and/or your ISDN service provider. Have the information that you recorded during hardware installation available.
8. Call Multi-Tech’s Tech Support department.
Startup Self Test LED Patterns
Each time the PRI card is reset (i.e., the CommPlete is powered on or the system reset is asserted) the PRI card firmware executes a series of startup self-test routines. The routines perform 8 basic tests which require a total of approximately 10-15 seconds to complete, and during which the yellow LEDs report the progress of the tests. The yellow LEDs display a test status pattern (the applicable LED is lit) as each test executes.
As each test passes, its pattern is displayed by the yellow LEDs. The subsequent test then begins execution and its pattern is likewise displayed. This process continues until the final test executes successfully, after which only the Frame Sync LED is lit for a short time, indicating successful completion of the startup selftest phase.
If any test fails, its LED pattern is flashed continuously at a 1/2 second rate and the PRI card will suspend further operations until the problem is fixed.
Run Time LED Status Indicators
On successful completion of the startup self-tests, the yellow LEDs display the real-time operating status of the PRI card hardware and software. In this mode, the LED meanings are defined by a COMM Engine
12 CommPlete Communications Server
3 Solving Problems
Process. The LEDs can be used for low-level troubleshooting of the ISDN connection. Some of the most common reasons for an ISDN connection failure are:
Problems involving HEART BEAT
• If the HEART BEAT LED is lit, it indicates the firmware has encountered an unrecoverable error. Verify that the firmware has had time to load properly and that processes are successfully completed. Call
Tech Support if the problem persists.
Problems involving PHY LINK LINK
• The ISDN circuit is not connected to the PRI card. If the PHY LINK LED is Off it indicates the absence of valid LEC circuit signaling. The ISDN circuit is not connected to the PRI card properly. Look for missing or broken wiring from the LEC distribution facility, malfunctioning interconnect cabling
(broken wires, bad connectors, incorrect connector installation, etc.).
Recommended action: contact your LEC representative.
Problems involving RED ALARM LED
The PRI card is experiencing a high error rate or is not configured properly. If the RED ALARM LED is lit, it indicates an improper receive signal or no receive signal. Check the configuration of the PRI card with the PRISTATUS command at the controller. Contact your LEC representative or Multi-Tech's
Technical Support Department if you continue to experience this alarm.
Problems involving YELLOW ALARM LED
The device at the other end of the network is in red alarm. It may not be receiving the signal from the
PRI card. Contact your LEC representative.
