iSAP1000 STM1/E1 Multiplexer

iSAP1000 STM1/E1 Multiplexer

The iSAP1000 is 1U 19” rack type STM-1/E1 terminal multiplexer which delivers traditional PDH services over SDH networks. iSAP1000 provides connectivity for up to 16E1. The product complies with SDH standards and interfaces with existing SDH backbones through a single or 1+1 protection STM-1 interface. iSAP1000 supports a variety of management access over console, Telnet and SNMP. iSAP1000 provides two Gigabit Combo ports (2-port 10/100/1000Base-T and 2-port 1000Base-X SFP slot) with 16x E1 or 2x STM-1 fibre interfaces. The two GE combo ports support Link aggregation, port based VLAN and 802.1Q VLAN function.
