8-Port Serial GPIM Interface Cables

 

All the ports of the 8-Port Serial Gigabit-Backplane Physical Interface Module (GPIM) are connected to two dual stacked 136-pin VHDCI connectors. Custom cables are used to connect from the VHDCI connectors to the data terminal equipment (DTE) or the data circuit-terminating equipment (DCE). Different cables are required to support different protocol and the protocols are identified using the cable ID. The cables are labeled with a letter (refers to the cable type) and 4 digits (unique serial numbers for the cables).

Table 1 lists the cables supported by 8-Port Serial GPIMs. You can order the cables from Juniper Networks to connect to a port on the synchronous 8-Port Serial GPIM. The device to which you are connecting and the serial interface types determine which type of cable you need.
