Description The ERM01 series product is a rack type E1 DSU/CSU for Fractional E1 Digital Access which is nested in a hub to provide an economic solution for central office installations. There are 13 slots available for G.703 E1 cards for installation into the ERM01 RACK. An optional SNMP card can be installed into the last slot for configuration and management, leaving 12 slots available for line cards.

Each E1 card may be linked to a remote E1/FE1 standalone Access Unit for various LAN, Video Conference, or Hosts over E1 network services. The ERM01 accommodates a redundant power supply as optional equipment, which may derive power from AC (90-250) or DC (-48V) power sources.
