Access Bank I

 

Easily provision varied analog voice services from T1

Compact device converts digital services to analog circuits
The Access Bankฎ I is an economical, compact device for converting T1 digital access services to 12 or 24 individual analog telephone circuits. Six different types of 12-channel and 4+8 channel telephone line interface cards provide a variety of analog line services, including:

  • BRFXS
  • DPO
  • DPT
  • E & M
  • FXO
  • FXS
  • FXSDN
  • PLARD
  • SPOTS
  • TO
  • The Access Bank I automatically adapts to changing line conditions, providing a clear, echo-free transmission path at all times.

    Minimize deployment time
    Designed for speedy deployment, the Access Bank I provides installation instructions right on the case. Configuration is done via DIP switches and self-test routines to ensure that all circuits are operable. The design incorporates an integrated CSU, allowing direct T1 line connection and monitoring.

    In-service maintenance capabilities include hot-swappable line cards, channel LEDs and fuseless protection of all interfaces. A remote management option with Windowsฎ GUI software and built-in modem is also available.

    Direct connection to full CLASS features
    The Access Bank I TR-08 option offers direct digital T1 connection to Class 5 local switch interfaces, eliminating the need for analog conversion of line connections at the Central Office. TR-08 signaling can be provisioned for physically separate shelves. Unlike trunk-side T1 switch connections, line-side TR-08 connections supply full CLASSSM features directly to customer phone lines.
