Operational Description
The Access Bank® I is an economical,
compact, remote terminal for converting T1 digital access services to 12
or 24 individual analog telephone circuits. The design incorporates an
integrated CSU, which allows customers to plug in a T1 line without
having to connect other peripheral devices. Six different types of
12-channel and 4+8 channel telephone line interface circuit cards
provide a wide variety of analog line services such as FXS, FXSDN,
SPOTS, PLARD, BRFXS, FXO, DPO, DPT, E&M, and TO. The Access Bank I
operates with high-speed modems and automatically adapts to different
line conditions, providing a clear, echo-free transmission path.
Designed to minimize deployment times, the
Access Bank I has all configuration information on the case, DIP
switches for configuration settings, and self-test routines to ensure
that all circuits are working before leaving the site. Installation
times are often no more than 30 minutes. In-service maintenance
capabilities include hot-swap line cards, line channel LEDs and fuseless
protection of all interfaces. A remote management option, with Windows®
GUI software and a built-in modem are available.
The Access Bank I is installed for
economical local or long distance T1 service delivery, modem pool
connections to T1, branch office connections, and the rapid deployment
of temporary telephone services. Systems integrators use Access Bank Is
to convert T1 equipment to a variety of analog service connections for
applications such as frame relay and IP telephony, computer telephony
integration (CTI), and voice port expansion of T1 digital switches.
The Access Bank I/TR-08 option offers a
direct digital T1 connection to Class 5 local switch interfaces,
eliminating the need for analog conversion of line connections at
carrier central offices. The Access Bank I/TR-08 T1 signaling can be
provisioned as physically separate A, B, C, or D shelves. Unlike
trunk-side T1 switch connections, TR-08 line-side connections provide
full CLASS® features to customer phone lines via the Access Bank
I/TR-08.
