power or for a battery backup
connection when using the AC
power source. For added
protection, the chassis features
a resettable circuit breaker. If
there‘s a short or power surge
on the incoming AC/DC line, the
breaker will trip to protect the
supply from damage.
The Compact T1 Channel Bank
offers several local and remote
management options. Cards can
be configured and managed locally
through either the RS-232 interface
(by using a VT100™ terminal, PC, or
modem) or via the Ethernet port to
the chassis’ T1 Controller Card.

For troubleshooting the channel
bank off-site, the chassis features
a dedicated, in-band DS0
management channel that provides
64-kbps remote access to the unit.
You can also use the 10BASE-T
Ethernet connection for out-of-
band SNMP network management
of TCP/IP networks. Daisychain
several channel banks and use
SNMP at a central network
management station to manage
both local and remote units.
For quick and easy
wallmounting, the Compact T1
Channel Bank comes with a
mounting bracket attached. We
also offer a rackmount kit for
mounting in a 19" rack or cabinet.
T1 Controller Card (Included)
The controller card that comes
with the chassis includes two T1
ports with integrated CSUs as well
as a built-in 1/0 cross-connect
matrix that provides full, non-
blocking connectivity between
the card and any of the cards in
the slots. To increase the total
T1 capacity of the Compact T1
Channel Bank to 18 network
access trunks or drop-and-insert
user connections, you would simply
add a full complement of 4-Port T1
Cards (MT854C) to the slots (for
more on the MT854C, see
page 3
).
Manage the T1 Controller Card
locally using its front-panel DIP
switches or through the Command
Line Interface (CLI) using an ASCII
terminal or PC with terminal
emulation software, or a modem
that uses XMODEM or PPP
sessions.
Six front-panel LEDs quickly
communicate alarm and T1 line
status, as well as mode of
operation. To manage the card
remotely, use either an in-band DS0
management channel or a separate
SNMP Ethernet connection.

The Compact T1 Channel Bank features a DS0 management channel , which you can use for SNMP management and remote access. This channel,
which enables full TCP/IP connectivity to a remote Compact T1 Channel Bank, can also be used for Trivial File Transfer Protocol (TFTP) upgrades of
the T1 Controller Card and service cards as well as remote Telnet access.
