Are V.35 serial interfaces supported?
WAN Cards (T1/E1 and V.35)Yes. A V.35 physical interface can be used in your test host using a serial card (S5141) from Sangoma. Normally, the V.35 interface should be connected to a CSU/DSU device.
The V.35 serial card is configured is configured in the same fashion as the T1/E1 card.
- The WAN protocol is configured to CHDLC
- The network protocol is configured to HDLC Streaming
In the case of connecting to a CSU/DSU, the clock setting should be set to external.
Here is an example wanpipe1.conf file:
