  • Page 9: Description

    Page 9 of 150 Description System overview The Mini-Carrier Remote (MCR) system, see Figure 1 on page 11, provides service for up to 128 analog and/or digital telephones over one or two T1 carrier links in a Meridian 1 system. Analog trunks at the remote site are also supported.
  • Page 10 Page 10 of 150 Description MCR consists of three circuit packs; two at the local site, the Local Mini-carrier Interface card (LMI) and Local Mini-carrier Extender card (LMX), and one at the remote site, the Remote Mini-carrier Interface card (RMI). At the local site, the LMI emulates two standard IPE line cards and can interface to the remote site via either one or two T1 carrier links.

  • Page 20: Functionality

    Page 20 of 150 Description Functionality The Mini-Carrier Remote system can be user-configured to use only certain time slots, in this way allowing “drop-and-insert” channel banks to use the time slots not used by MCR. This allows customers to use LAN bridges via the remaining time slots to connect between local and remote LANs.

  • Page 22 Page 22 of 150 Description DIP switches Three cards have DIP switches that must be configured prior to card insertion. On the LMX, DIP switch settings identify the LMX’s position with respect to the LMI and RMI. DIP switch settings on the LMI and RMI determine binary daisy chain address, T1 line build-out, framing mode, terminal baud, and terminal settings.
  • Page 23 Re-insert the card and lock it in place with the ejector tabs. If the LEDs still do not flash three times, contact a sales representative about returning the card to Nortel for repair or replacement.
  • Page 24 Page 24 of 150 Description As long as the digital set is off-hook, it retains the time slot. An MCR user may place a call on hold, make a second call, and switch between calls. However, the call on hold is not occupying a time slot. If the user places the digital set on-hook while there is still a call on hold, the time slot is lost, but not the call.
  • Page 25 Also, if the local card receives a cardLAN message that is undefined, no attempt is made to answer that message. Should the existing Nortel line cards be updated such that they operate on an expanded cardLAN message set, the MCR system must also be updated.
  • Page 26 Page 26 of 150 Description When the T1 framer is configured for D4 operation the firmware uses bi-polar violations instead of CRC-6 errors. When using bi-polar violations, the total number of bi-polar violations are used as CRC-6 errors in the above calculations.
  • Page 27 Description Page 27 of 150 ESAM is intended to be used, primarily, in the case of an interruption in service from the T1 carrier links serving MCR systems. A two-position faceplate switch on the RMI, like the LMI, sets ESAM mode as always active or requires that ESAM switchover be determined through each location’s MMI configuration.

  • Page 29 Description Page 29 of 150 When a call comes into a trunk, all telephones that are on-hook with an unused line will ring and the lamp associated with the unused line will flash (if both lines are unused, the primary line’s lamp will flash). Telephones that are off-hook with an unused line will get a flashing lamp associated with the unused line and a warning tone.
