Internal PVM
The PVM supports up to 128 channels, depending on the voice codec and
the voice license agreement you use. For information about the supported
voice codecs and the voice-related licensing, see Nortel Secure Router
4134 Configuration — SIP Media Gateway (NN47263-508).
The PVM is an internal module and is not directly connected to any
external interface.
ATTENTION
You cannot enable the management port on the rear of the Secure Router 4134
(Ethernet 0/0) if you have a PVM installed (this is related to hardware design).
Ensure you use Ethernet 0/1, 0/2, 0/3, or 0/4 for management if you use a PVM
in the router.
The PVM is field-replaceable, but is not hot-swappable.
