i have question for you, NM-2V and NM-HDV-2E1-60

nm-2v is just used for plain phone,

the nm-hdv-2e1-60 is just used for IP phone,

see :

Plain phone---PBX-2620(NM-2V)-----WAN

IP phone--switch--2620(nm-hdv-2e1-60)----WAN.

I don't know my thinking is correct or not

thank you in advanced

Not exactly. Although the VWIC can be used for WAN connectivity, typically it is used for digital voice. So a couple examples of how it may be used:

Phone---PBX---NM-2V(2620)---WAN

IP Phone---Switch---(262)NM-HDV-2E1-60---PBX/telco using ISDN or E1/R2

According to your points,

it also may be used:

phone---PBX--NM-HDC-2E1(2620)WIC---WAN,

IF so ,the NM-HDC-2E1 can support 60 voices,but AS5300 just supports 120 voices, so the 2620 with NM-HDC-2E1 is more efficient, that is right?
