The
Telinc TL3552 T-1 CSU/DSU provides the interface between customer
equipment and a T-1 or fractional T-1 facility. It supports
D4 or ESF framing with AMI or B8ZS coding and includes twenty-one
front panel indicators that show complete status on a full
time basis.
Two
User Channels
The
TL3552 provides two user channels, a synchronous channel and
a DSX1 drop-and-insert channel. Unlike competing units, the
Telinc DSX1 channel includes a long-haul T-1 interface which
can be connected to another T-1 CSU/DSU located up to 6000
feet away. The TL3552 is also available without the DSX1 channel
as the TL3550.
The
synchronous channel can operate at any multiple of 56 or 64
Kbps. V.35, RS232 and RS530/RS422 interfaces are included
as standard. The twenty-four DS0s may be given to either the
DSX1 or synchronous interface or allocated between them on
a contiguous or non-contiguous basis. Timing can be from the
network, from the synchronous channel, from the DSX1 channel
or internal. |
SNMP
Management
TL3552
T-1 CSU/DSUs can be controlled from the front panel, from
a local or remote ASCII console or from an SNMP management
platform. Like other Telinc products, TL3552 units include
an embedded SNMP agent and are MIB II-compliant. They support
SNMP gets, sets and traps. The TL3552 can also be configured
with DIP switches conveniently located behind the front panel.
Each switch is clearly marked.
Full
Time Status Reporting
Twenty-one
LEDs show full operating status at all times. Testing of the
local and the remote, unattended unit is initiated using front
panel switches or from the console. Front panel monitor jacks
on the customer interface provide convenient access for external
test equipment.
Multi-Unit
Installations
The
TL3552 console port supports dial modems and VT100 terminals.
Up to eight units can be daisy-chained together and controlled
by a single console. A rack mount frame is available for mounting
up to eight units. |
