[cisco-voip] 3845 DSP

[Justin Steinberg]

nick do you know if this 15.1(T) feature will be require PVDM3s ?

Assuming the 15.1(T) ISRg2 terminates the TDM PSTN connection, will V90/32
work for fax/modems that connect via a VG224 ?    Or will this only work for
devices off an FXS on an ISRg2 with PVDM3s and 15.1(1)T ?
