System Configuration Introduction – p. 18
The V312 is identical to the V311 but has two E1/T1 interfaces instead of one.
The WMTS at the head end requires one or two E1/T1 interface cards (plugged
into the rear slots, with the second E1/T1 card attached to the first one as a
daughter board) to work with the V311 or V312. The E1/T1 connection will be
terminated at one of the ports on this (rear) E1/T1 interface card(s). In addition,
a separate software load is required.
All modems have four LED indicators, described below.

The V313 is a V280 (for the DOCSIS layer) with a PSTN interface added: this
physical interface (provided with the V313) comprises four RJ45 connectors,
each of which connects to a special cable terminated in four RJ11 connectors,
allowing a total of sixteen PSTN devices to be connected.
The WMTS at the head end requires an E1/T1 card and a V5.2 AN stack
(additional software available from Vyyo) to work with this unit. If you plan to
deploy the V313 please contact your Vyyo representative.
