TRM01

Managed T1(DS1) Concentrator

The TRM01 is a 4U 19(23)" rack type T1 DSU/CSU for

unframed T1 and Fractional T1 Digital Access which is nested in

a hub to provide solutions for central office installations. There

are 13 slots available for hot swappable T1 (DS1) cards for

installation into the TRM01 rack. An optional SNMP card can be

installed into the last slot for configuration and management,

leaving 12 slots available for T1 (DS1) cards. The SNMP card

provides both local control via an RS-232 serial console port and

remote management using industry standard SNMP protocol via

an Ethernet 10BASE-T connection. Each T1 (DS1) card may be

linked to a remote T1/FT1 stand-alone Access Unit for various

LAN, Video Conference, or hosts over T1 (DS1) network

services. The TRM01 accommodates an optional second hot

swappable shared power supply module which may derive power

from AC (90-250) or DC (-48V) power sources. On the rear panel,

combinations of RJ-45 and wire-wrap terminals are utilized for T1

(DS1) Line interface connections. Adapter cables are used to

convert the HDB26F DCE data ports to V.35, RS-530, RS-449,

X.21 or 10/100 Base Ethernet depending on the installed card.
