Operational
Description
The Access Bank® II includes two T1
network interfaces with fully-integrated CSU/DSUs for over 3.0 Mbps of
total bandwidth. The dual T1 interfaces can be utilized for any
combination of voice and high-speed data services, automatic
protection of T1 network connections, and drop and insert
applications.
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 II operates with high-speed
modems and automatically adapts to different line conditions,
providing a clear, echo-free transmission path.
In-service maintenance capabilities
include hot swap line cards, line channel LEDs and fuseless protection
of all line interfaces. Deployment time is minimized with simple
configuration information printed on the case, along with DIP switches
for manual activation of settings and test functions while on-site.
Configuration and tests are available
through several management software options. For configuring,
monitoring, and testing, a Windows®-based GUI program is included. In
addition, an embedded SNMP Agent is accessed via a 10Base-T Ethernet
port. Remote T1 management is available from Carrier Access' Access
Navigator™, without using customer bandwidth.
Carriers and end-users install the Access
Bank II for multi-line voice plus high-speed data services, long
distance access, branch office voice and data connectivity, protection
of mission critical T1s and the integration of fax, modem, high-speed
data and digital PBX connections on access T1s.

Installation Kit
SpeedwayTM
Installation Kit (for Access Bank or Access Exchange units)
Your installation is literally a snap. This Kit uses locking tabs and
pins, versus screws, to install up to two Access Bank or Access
Exchange units. Customer installation tests have shown up to a 75%
reduction in installation time, as well as up to a 45% smaller
footprint.
