T1 CSU/DSUs
Terminate T1/FT1 and convert to V.35,
RS-530, or Ethernet.
Key Features
Connect to V.35,
RS-530, or 10BASE-T terminal interface types.
VT100™ control port with full DS0 mapping.
Nx56-/64-kbps channel selection with speeds up to
1.544 Mbps.
Loaded with diagnostics.
Available as a card for the Managed
MicroRACK.
T 1 CSU/DSUs terminate T1/FT1 circuits over a 4-wire RJ-48C interface. They convert this interface to V.35, RS-530, or
10BASE-T, depending on model.
T1 CSU/DSUs are an excellent choice for terminating leased lines, Frame Relay backbones, and Internet access. They support
Nx56/Nx64 kbps T1 framing as well as D4/ESF framing options and AMI/B8ZS/B7ZS line coding, plus internal, external, and network clocking.
Data rates, framing, and coding options are programmed by DIP switches or through the consol port from a VT100 terminal or terminal emulator.
A full range of system and diagnostic features make setup simple. T1 CSU/DSUs respond to central-office-initiated D4 loopup and loopdown codes, ESF line loop, and payload loop FDL messages. They’re compatible with three V.52 (Bit Error Rate) test patterns and both local and remote Telco diagnostics.
T1 CSU/DSUs support framed Nx56/64 kbps rates up to
1.536 Mbps and unstructured rates to 1.544 Mbps.
The 10BASE-T model is particularly suited for LAN-to-LAN connection. MAC forwarding and
PPP/BCP built-in bridging provides seamless connection over the T1 link without the need of routers. PPP/BCP also enables you to extend a router’s serial interface for connection to a remote Ethernet LAN over the
T1 network.
T1 CSU/DSUs are available in a choice of V.35, RS-530, or
10BASE-T interfaces. Choose from a standalone version or a rackmount card which fits into our
Managed MicroRACK.
Managed MicroRACK
When space is at a premium, choose the 16-Port Managed
MicroRACK system. It holds up to
16 cards and fits into only 2U of rack space.
The MicroRACK accepts one or two AC or DC power supplies in any combination. Each power supply is capable of providing
100% of your rack power requirements. In the event of failure, the other supply immediately takes over and the
MicroRACK notifies you of the power failure.
The network management module enables you to configure, control, and perform diagnostics using SNMP or HTTP over a
10BASE-T Ethernet connection.
