Cisco - Router - 2600 - Notes

Shopping list for router supporting analog modem dial-in (Configuration verified. See: Hardware - Dialup - Dialup at home):

• Cisco 2600 Series Router
• 1x NM-2V
• 2x VIC-2FXS
• 1x VWIC-1MFT-E1
• 1x AIM-VOICE-30

Maximizing the FXS ports in a 2600 series router ( Configuration to be verified. ):

• 2600XM series or 2691 router.
• 1x NM-HD-2V
• 2x VIC-4FXS

T1/E1 Multi-Flex Trunk VWICs VWIC-1MFT-T1, VWIC-2MFT-T1, VWIC-2MFT-T1-DI can be used for either voice and data or both.
Use as a Voice Interface Card requires a Digital Signal Processor (DSP) to exist exist on the network module (NM) in which the VWIC is instaled.
Appropriate NMs such as an NM-HDV, NM-HDV2, an NM-HD-2VE, or an AIM-VOICE-30 and AIM-ATM-VOICE-30.
If installed in a standard WIC slot in a 2600 or 3600 router instead of the WIC slot in a network module (NM) it will function as a WIC wihtout the Voice support, unles an AIM-VOICE-30 or AIM-ATM-VOICE-30 module is also installed in the router.

Key Note: Before the introduction of the AIM-VOICE-30, providing digital voice service required the
NM-HDV and analog voice services required the NM-1V/2V or NM-HDA. The AIM-VOICE-30, when used with a
Voice/WAN interface card (VWIC-MFT), can provide digital voice service without using teh NM-HDV.
This frees a valuable network module slot for other applications.
