10/100 BASE-T INTERFACE


The LAN connection on the 4280, 4284, and 9480 is a 10/100 BaseT interface on the
front of the unit and is labeled “LAN”. The interface requires a standard RJ45 terminated
Category 5 twisted-pair data cable. It connects to a 10/100 Hub, EtherSwitch, or router
on a local LAN segment providing access to a wide-area IP based network. This port
supports TCP/IP peer-level protocols (e.g. TELNET, TCP, IP, ARP, SNMP, etc.). The
LAN interface will automatically negotiate the speed with the network interface PHY. The
4000XA and 4180 provides two LAN connections with similar interface capable of
10BaseT operation. These are labeled LAN and GATE for their distinct functions.

3.6 TSR

The 4000XA and 4180 DSU interface uses an industry-standard RJ48C connector. The
option of using the interface for T1 (1.544 MHz) or E1 (2.048 MHz) is software
selectable. The TSR is used to transport individual time slots with on T1/E1 interfaces.

3.7 USER

PORTS


The user serial ports support both asynchronous and synchronous protocols in either
DCE or DTE modes. Configuration is selectable on a per port basis. Baud rates up to
115.2kbps are supported. Synchronous ports support NRZ & NRZI. The NRZI format
supports recovered clocks for isochronous (i.e. 2 wire) operation.

The V.35 and RS-530 interfaces require a 9008 adapter, or a 9116 intelligent patch
panel. The RS-232 physical interface may be done via the 9116 intelligent patch panel,
or directly from the user port interface. When using a RJ45 interface, an industry
standard RJ45 to DB25 adapter is utilized. The 9008 adapter and the 9116 intelligent
patch panel each provides a DB25 interface. See the cabling information contained in
this user manual.
