PVDM Requirements


This appendix lists the packet voice/data module (PVDM) requirements for MRP and ASI cards.

Default DSP Software Images

The type of software image (high-complexity image or medium-complexity image) that is loaded on multiservice route processors (MRPs) and analog station interfaces (ASIs) affects the processing of traffic on these cards. The default values for DSP software images on MRPs and ASIs are as follows:

High-complexity image. VIC-2DID, VIC-2BRI-NT/TE, VIC-2FXS, VIC-2FXO-M2, VIC-2FXO-M3, VIC-2FXO, VIC-4FXO-M1, VIC-4FXS/DID, VIC-8FXO-M1 (MRP3-8FXO-M1), VIC-2E/M, VWIC-1MFT-T1, VWIC-1MFT-E1, VWIC-2MFT-T1, and VWIC-2MFT-E1.

Medium-complexity image. VIC-4FXO-M1, VIC-4FXS/DID, VIC-8FXS (MRP3-8FXS and ASI81), VIC-16FXS (MRP3-16FXS and ASI160).


Note The PVDM requirements listed in Table B-1and Table B-2 are based on the assumption that you are using the default DSP software image for a particular voice WAN interface card (VWIC) or voice interface card (VIC).


PVDM Requirements for MRPs and ASIs

Table B-1 lists general guidelines for PVDM requirements for MRPs and ASIs. For detailed guidelines, refer to Table B-2.

Note Table B-1 does not address transcoding. For information about transcoding considerations, see the "Transcoding" section on page 6-24.


Table B-2 shows the PVDMs that are required for the supported combinations of WAN interface cards (WICs), VWICs, and VICs in MRPs and ASI81s. WICs, VWICs, and VICs are referred to by the abbreviations given in Table 1-1.

As Table B-2 indicates, WICs and data-only VWICs do not require PVDMs.


Note The typical PVDM configuration for MRP3-16FXSs ASI160s is a PVDM-16 in each of the two PVDM slots.
