configuration with interfaces including ATM, Synchronous Optical Network
Technologies (SONET), ISDN BRI, ISDN PRI,T1, E1,T3, and E3. It also supports
AVVID applications through use of the multiservice interchange (MIX)
functionality.The MIX allows the 7200 to support digital voice as well as
gateway functionality through the use of two different trunk interfaces, the highcapacity
and medium-capacity T1/E1 trunk interface cards.The primary difference
between the two cards is that the high-capacity card includes an on-board
DSP card for compression.The 7200 Series can support up to 120 voice calls
depending on the module configuration used.This router also supports analog
voice applications through the use of voice interface cards (VICs).
