T1 Controller Card
Overview
Overview
The Compact T1 with the Dual T1 Controller Card offers a cost-effective, compact
solution that delivers a wide range of services from both wireline and wireless access
networks. The T1 Controller Card includes two T1 ports with integrated CSUs and a
built-in 1/0 cross-connect matrix providing full, non-blocking connectivity between the
T1 Controller Card and any of the six service card slots. The total T1 capacity can be
increased to 18 network access trunks or drop-and-insert user connections by adding a
full complement of Quad T1 Service Cards.
The Compact T1 offers a modular design that includes the T1 Controller Card
(required) and an array of available service cards. This flexibility allows the Compact
T1 to function in a variety of applications, including:
l
1 to 18 T1 multi-service digital cross-connect system
l 48 FXS/FXO/DPT channel bank
l 24 FXS Voice over IP (VoIP) Customer Media Gateway (CMG)
l 40 ISDN BRI shelf
l 6 Ethernet IP Router/WAN nest
l 2 to 12 V.35 or synchronous RS-232 port drop-and-insert CSU/DSU
l 1 to 24 OCU-DP digital data service (DDS) delivery device
The modular Compact T1 platform also allows service providers to scale across service
types, network architectures, and bandwidth requirements to fit a dynamic service
delivery environment. Service cards provide the physical, electrical, and logical
connections for either customer service demarcations or network access. Any service
card can be placed in any service card slot. In addition, the (CMG) Service Card
enables the Compact T1 to provide a cost-effective migration path to packet-based
softswitching infrastructures using the MGCP protocol for both existing TDM-based
infrastructures and Greenfield VoIP applications.
The T1 Controller Card has several local and remote management options available.
The card can be configured and managed locally using the front-panel DIP switches or
the Command Line Interface (CLI). Front-panel LEDs quickly communicate alarm
and T1 line status, as well as mode of operation. Remote management is accomplished
directly either over an in-band DS0 management channel or via a separate SNMP
Ethernet connection.
