Multiplexer Unit : Apr 2003
The 4-CHANNEL T1 Port Card provides four RJ-45 (100 Ohm balanced) connectors
for T1(DS1) Line interface connections and supports four separate T1 (DS1) channels at a
transmission rate of 1544Kbps (transparent unframed T1) each.
The 4-CHANNEL Data Port Card provides four standard nx56/nx64Kbps, up to
2048Kbps for V.35 (or X.21, RS-530, RS-449, RS-232) DCE ports on MB34 (DB15,
DB25, DB37, DB25) female or male connectors (required adapter cables optional) for
direct connection to terminal equipment.
The Ethernet Bridge Port Card provides an RJ-45 connector for 10Base-T or
100Base-TX Ethernet (auto negotiation) connections. The bridging function provides LAN
to LAN segment links which operate under the same network address space.
When any port card is inserted in a slot, LEDs on the front panel will show both the
channel statuses and any alarm indications.
The
MULTIPLEXER UNIT
E1 and T1 Interface Cards fully meet all E1 and T1
specifications including ITU-T G.703, G.732, G.733, G.823 and G.824. The Bridge
Interface Card meets all Ethernet specifications for IEEE802.3 and IEEE802.3u.
Each 4-CHANNEL Port Card features diagnostic capabilities for performing local
loop back or remote loop back (except for Ethernet Bridge card). The loop back function is
controlled by the front panel LCD menu, terminal mode (RS-232 console) or via option
SNMP.
Up to five clock source selections are provided. Without the external clock card option,
the unit operates from clock recovery only. When the external clock card option is installed,
additional clock sources may be selected from an additional internal oscillator (located on
the option card) or from an external clock references for E1 PCM, E1 TTL, T1 PCM, or T1
TTL. All E1 and T1 connected equipment must recover or slave their timing to the
MULTIPLEXER UNIT's
internal oscillator or from an external reference clock (with
option).
When the
MULTIPLEXER UNIT
is ordered with an optional SNMP Card , the card is
installed inside the chassis. Configuration is accomplished via local control on the
asynchronous RS-232 port with a standard VT-100 terminal, via Ethernet and Telnet, or via
any standard SNMP network management software over Etherenet. If the SNMP Card
option is not installed, local and remote management are still possible via the units internal
menu system accessible from the front panel LCD and menu keys, or via the asynchronous
RS-232 port with a standard VT-100 terminal.
