The ETU02-MUX is a 1U 19(23)" 4 slot rack mountable
multiplexing solution for Fractional E1 network services. Up to four
DTE devices may be linked to this model at data rates of 64Kbps
to 2048Kbps. There is also provision for one optional E1 sub-link
which will perform drop & insert with user-defined timeslot
connections from a PABX or other E1 equipment to E1 network
services. The Fractional E1 2 or 4 port multiplexer supports local
control and diagnostics via an LCD display and LED status
indicators located on the front panel or via a serial console port.
These features enable users to easily configure the unit, execute
the in-service diagnostics and monitor the network status. The
ETU02-MUX provides for optional SNMP Network Management
System, which allow the user to remotely control and manage the
system via SNMP protocol. This model fully meets all of the E1
specifications including ITU-T G.703, G.704, G.706, G.732, and
G.823.
Provides 4 slots, removable interfaces: V35, X21, RS530, RS449,
RS232, G.703 Co-directional, NRZ, Ethernet Bridge and Router.
Optional drop and insert E1 port (Sub E1)
Built-in BERT with V.54 diagnostic capabilities for performing local
and remote loopback
