  • Page 4: Introduction

    When providing both E1 and T1 network connections from the same cPCI card, standard practice is to set the top module (ports 0-3) as E1 and the bottom module (ports 4-7) as T1. It is not possible to have mixed E1/T1 ports on a single PM module.

  • Page 5: Uses Of The E1/T1 Cpci Card

    Note The E1/T1 cPCI card is not a complete product, and only has usable functionality when associated with a host chassis and an application program. Telephone network attachment The E1/T1 cPCI card with revision 1.5 E1 PM4 Line Interface Modules fitted, attaches to the 2Mbit digital system or Primary Rate (2.048 Mbit/s) Integrated Services Digital Network (ISDN).

  • Page 6: Ohm Network Connection

    Different impedance can be supported on the same E1 variant module; Note The revision 2 modules can simultaneously support both E1 and T1 ports. Earlier revisions could only support either E1 or T1 as they required different E1 or T1 variant modules.

    There are two categories of multi-channel path provided by the card. The figures in part 1 below are for one PM4 module. The fitting of a second E1 or T1 PM4 module will increase the call handling capacity accordingly.

    There is a single blue LED on the end plate of the E1/T1 cPCI card. Only when this LED is lit is the card then ready to be fully removed. Press the red release button to unlock the upper lever, then simultaneously operate both levers and slide out the card to fully remove it.

  • Page 10: E1/T1 Cpci Card Led Usage

    E1/T1 cPCI card LED usage The Aculab E1/T1 cPCI card has a block of eight LEDs visible on the endplate of the card. These LEDs are labelled, and each one corresponds to a port on the card. If the card is fitted with one PM4 module, then the LEDs for those four ports will operate and the LEDs for the unused ports will be off.

  • Page 11: Approval Information

    This section provides information on the Approval of the E1/T1 cPCI card, and information that may affect the Approval status of the card in use. Failure to use the E1/T1 cPCI card in accordance with any of these instructions may invalidate the Approval for connection.

    H.110 CTBus clock. The jitter performance required to maintain the card's approval status is only guaranteed if the external clock is derived from another Aculab E1/T1 cPCI digital network access card that is connected to the system. Other clock configurations may require further testing to ensure compliance.

  • Page 22 Operational code running from RAM Speech calls If the E1/T1 cPCI card is used in an application that makes or answers calls with a service code that indicates a speech or telephony call, or any call that may use a partly analogue route, there is a requirement that audio signals transmitted are encoded using CCITT A-law PCM, and do not exceed a 1 minute mean power level of -9dBm.
  • Page 23 If in doubt, seek advice from a competent telecommunications safety engineer. In order to maintain the host independent approval of the E1/T1 cPCI card, it is essential that when other expansion cards are introduced which use or generate a hazardous voltage, the minimum creepage and clearances specified above are also maintained.
