ETSI/ITU V5 Interface¶

The V5 interface was introduced into digital Central Office / Telephone exchanges as a vendor-independent, standards-based interface for aggregating subscriber access lines.

See this video recording of a presentation for more information about this interface.

We have acquired a number of V5 access multiplexers (AN).

laforge has started an implementation of exchange (LE) side V5 protocol stack which jolly later completed.

V5 Access Networks¶

A number of vendors produced related equipment series:

• Siemens (Fastlink)
• Nokia EKSOS
• DeTeWe ALIAN

Talking to a V5 access network¶

In order to talk to a V5 acces network (AN), you need to emulate the phone switch (LE).

We have created the osmo-v5 software to do exactly that.
