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:

PVDM Requirements for MRPs and ASIs

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

General DSP Configuration Rules

Note   On MFT-T1 and MFT-E1 cards, medium-complexity firmware is not recommended, since the use of this firmware limits echo cancellation coverage to 16 ms (also note that 33 percent more voice channels are supported on each DSP when medium complexity firmware is used). In addition, these cards, when installed in MRPs or ASIs, support up to one payload of T1 (24 channels) or E1 (30 channels) voice traffic.
Note   Table 5 does not address transcoding. For information about transcoding considerations, see the "Transcoding" section later in this paper.

Table C-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 C-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.
