Description

MAPLE-4CSis a compact and cost-effective Managed multi-service multiplexer with 256 time-slot cross connect ability, with one slot for uplink card including 4E1/8E1 and PDH optical interface and 3 slots for downlink cards including FXO, FXS, E&M, RS232 and fractional Ethernet/V.35 to E1. The 1+1 port protection of 8E1 uplink card makes sure all services work continuously when one link breaks down.
MAPLE-4CSintegrates multiple dedicated data, voice and LAN channels over multiple main (network) links. It provides full range of voice and digital data services to subscribers located at different locations require to interconnect and establish a voice and data network over E1 link. It has wide application, including electric companies, industry as well as railway and airports
MAPLE-4CScan be deployed either in point-to point topology or point to multipoint topology. It can be managed via local CLI or Telnet/SNMP and also through a centralized GUI based Liteview NMS.
