Thank you jim,

Found a link at
http://www.cisco.com/en/US/partner/products/ps6441/products_feature_guide091
86a00806b941f.html

But reading that page makes me believe these PVDMs are only sopported on the
motherboard with an NM-1CE1T1-PRI or the dual version. And not on an NM-HDV2
mobule which is a shame, regarding upgrades and compatibility.

List price wise I'm also not in favour of these cards, the voice capable
PVDMs are a lot cheaper. Even the upgrade PVDMs are well priced at $50 (per
DSP-1) less than buying a new module.
PVDM2-12DM	12 Port Digital Modem Module	$2,350
PVDM2-24DM	24 Port Digital Modem Module	$3,995
PVDM2-36DM	36 Port Digital Modem Module	$4,995

VS.
PVDM2-8	8-Channel Packet Voice/Fax DSP Module	$400
PVDM2-16	16-Channel Packet Voice/Fax DSP Module	$800
PVDM2-32	32-Channel Packet Voice/Fax DSP Module	$1,600
PVDM2-48	48-Channel Packet Voice/Fax DSP Module	$2,400
PVDM2-64	64-Channel Packet Voice/Fax DSP Module	$3,200

Am I missing something here?

Has anyone used an VWIC-2MFT-T1/E1 to terminate modem or voice calls on
DSPs?
