Power supply options for 110V AC, 220V AC or -48V DC, ensure maximum flexibility for central office installations. This equipment complies fully with all

ITU-T standards for E1 transmissions. The modules are hot-swappable, capable of automatic switch over in case of module failure, stable, and reliable.

Power Redundancy

The ERM-MUX/PLUS supports complete redundant functions for the electrical input service, the power module cards, CPU card and E1 card. The E1

backup provides 1+1 modes. All of these cards are capable of automatic switchover in case of failure. The system has complete warning and

diagnostic functions for stable and reliable operation.

1+1 Redundant

System supports performance monitoring and BERT test through NMP or Terminal console according RFC 1406 recommendation. CRC-4 and BPV

monitoring: CURR ES / UAS , LONG ES / UAS. Loopback test and BERT test: display Rx error amounts, Error counts and Bit-error-rate. Test patterns: 2e9-1,

2e11-1 and 2e15-1. Error Insertions and rates: Single, 10e-1, 10e-2, 10e-3, 10e-4, 10e-5, 10e-6, 10e-7.

Performance and BERT test

Network Management

The ERM-MUX/PLUS supports SNMP and/or NMP GUI network management with local PC or via a dedicated timeslot from the E1 line. The NMP GUI can

manage more ERM-MUX/PLUS equipment via the E1 network in-line or in nested structures. A console terminal mode is supported as well. When SNMP

management mode is available and selected, remote Telnet and HTTP embedded web server are also available for management.

1. Terminal mode: Configuration by local RS-232

serial port; Maintenance & alarm.

The intelligent NMS provides the support that the network manager needs. It consists of three parts :

2. MIB file SNMP: Configuration by RJ-45 10/100

Ethernet port; Complies with MIB-II standard.

3. GUI SNMP: Configuration by RJ-45 10/100 Ethernet port;

Real time monitoring & trap alarm in Window® graphic mode.
