Centralized integrated service access platform
M35_ZMUX-3300 Cross connect card

M35

Cross connect card

    The M35 cross connect card can be used to insert any common service board slot of the ZMUX-3300 platform,which realize 16channel E1 full-slot cross-connect function.

Product description

The M35 card has two DB37 connectors. Each DB37 connector can access 1~8channel E1 signals and provide 16channel E1 interfaces,to realize 16channel E1 full-slot cross-connect function.

The M35 card provides a flexible switching network that enables non-blocking full cross-connections of any 64k channel between 16channel E1. It has the ability to process the associated channel (CAS), which can extract the synchronous clock through the line or generate a synchronous clock of the inside device
