The V5 standard offers significant advantages to Carriers in providing an open standard interface supporting end-user narrowband services in a efficient and cost effective way. Different from V5.1, more capable V5.2 may support up to sixteen 2.048Mbits links on one interface and support ISDN PRA user ports. A capability of traffic concentration is also another features of V5.2.

MSAP2000 provides the standard V5 interface which complies with ITU-T G.964, G.965 and G.965 supplementary protocols. It has also passed compatibility testing with local switches: Lucent BZ5000, NEC NEAX, and SIEMENS EWSD. Our V5P solution supports V5.2 protocol and can provide up to four individual V5.2 (4xV5.2). Each V5.2 is capable of the maximum support to 16 E1 interfaces which provide up to 480 voice channels with non-concentration. This allows the service providers to provide both on-demand and leased line services, including PSTN Access, ISDN BRI/PRA, Analogue and Digital Leased Line. By provisioning to support 1:N concentration rate, V5.2 will allow saving of switch port, transmission equipment and transmission media cost.

The services provided through E1 with the V5.2 protocols can be also ensured reliability through communication channel protection that allows assignment of a secondary 2.048Mbits link as a channel back-up
