Packet Voice Support
On the voice network modules, the basic voice connectivity is as follows:
• The 1-port T1 Multiflex VWIC connects 1 to 24 DS0 channels (voice calls) to the network module
• The 2-port T1 Multiflex VWIC or 2-port Drop and Insert T1 Multiflex VWIC connect 1 to 48 DS0 channels (voice calls) to the network module
• The 1-port E1 Multiflex VWIC connects 1 to 30 DS0 channels (voice calls) to the network module
• The 2-port E1 Multiflex VWIC or 2-port Drop and Insert E1 Multiflex VWIC connect 1 to 60 DS0 channels (voice calls) to the network module
See the data sheet of each network module (NM-HDV, NM-HD-2VE, and NM-HDV2) for further details.
