V.110 Support for Cisco 3600 Series Digital Modems
The type of display output generated from the show modem slot/port command depends on the version
of Cisco IOS software running on the router or access server. For example, the following example shows
an example output for a 56K modem card, which carries digital modems that transmit at 56 kbps.
Note
56K modems do not modulate or demodulate data. A pure digital-to-digital connection is
made.
See Table 2 for a description of the fields displayed by this modem card.
