Overview
Overview
V.35 Service Card
The V.35 Service card enables service providers and enterprise network
managers to provision connectivity to high-speed serial synchronous Data
Terminal Equipment (DTE) devices such as routers, Frame Relay Access
Devices (FRAD) and video conferencing equipment.
The V.35 Service card provides scalable high-speed data service capacity to grow
with user needs. Up to six V.35 cards can be inserted into any slot of the Compact
T1 Customer Service Terminal, providing up to 12 fractional T1 V.35
connections from two T1 network connections. Two Adit Quad T1 Network
Access/Drop-and-Insert cards allow eight T1s with full T1 CSU/DSU
functionality to be terminated to eight V.35 ports in a single Compact T1. The
Adit’s digital cross-connect functionality offers service grooming, T1 drop-and-
insert, and voice access integration that are not available in traditional CSU/DSU
offerings.
Each V.35 port supports any n x 56/64 Kbps rate up to 1.536 Mbps. Both ports
may operate simultaneously at any supported speed. Flexible clocking allows
loop timing from any T1 line and provide system clocking to the connected DTE,
supporting a wide range of data networking applications.
Local and remote management options for the V.35 cards are available through
the Compact T1 Controller. The cards can be locally configured and managed
using CLI.
V.35/54 Service Card
Additionally, each V.35 port supports V.54 loopback test capabilities. This
feature enables V.54 loopback pattern recognition, generation and timing control
to troubleshoot service from the network or the end device to the V.35 electrical
interface. Four standard Bit Error Rate Test (BERT) patterns and an error counter
are provided for testing.
