Clarification needed for ISDN interface cards

[krishnamurthy.mh]

Hi,

What is the difference between these ISDN BRI cards(functionality):WIC-1B-S/T and VIC-2BRI-NT/TE.

In place of WIC-1B-S/T can i use VIC-2BRI-NT/TE interface module???

Regards,

Hello Krishna,

BRI S/T

(external NT1)

see

about the other one VIC stands for voice see the compatibility matrix

http://www.cisco.com/en/US/products/hw/routers/ps259/products_tech_note09186a00800e73f6.shtml

depending on the router you may need the right network module

two notes:

1)

because a VIC-2BRI-S/T-TE exists the physical layer can be different.

2) the WIC cab be good also for data services the VIC may be used only for voice services so it depends on application

Hope to help
