V5 Access Multiplexers (Access Networks)¶
The so-called V5_Interface was specified by ETSI and ITU as a standardized, interoperable interface between the heart of a digital telephone switch and (possibly remote) access multiplexers. The exchange side is called LE (Local Exchange) and the access multiplexer is called AN (Access Network). They are interconnected over an E1 (ISDN PRI) intreface.
