NM-HDV2-2T1/E & shipped in DSP


i found-

"Plan for the Number of DSPs Installed

This section is true for the DSP Single In-line Memory Modules (SIMMS). The High Density Voice Network Modules (NM-HDV) Farm module ships with two SIMMS and is able to handle three additional SIMMS. Each SIMM contains three DSPs. Each DSP supports four transcoding sessions or one conference bridge. Four transcoding sessions are supported for 729-711. If you use the Global System for Mobile communication (GSM), then the DSPs can handle three transcoding sessions. Therefore, the maximum number of transcoding sessions that a five-SIMM configuration supports is 60 transcoding sessions. The maximum number of conference calls that a five-SIMM configuration supports is 15."

Does it mean that NM-HDV2-2T1/E1 also contain shipped in DSP ?

No - that module doesn't come with DSPs, you need to buy an appropriate amount for your scenario.

Re: NM-HDV2-2T1/E & shipped in DSP

In the first gen module NM-HDV, you could order them with or withoutDSP chips in it. The NM-HDV-FARM was sold as a transcoding/conferencing resource and comes with 3 or 5 DSP chips in them. The NM-HDV2s are not available in this flavour. You just need to get the PVDM2's separate. Also the NM-HDV2s have only 4 slots.(not 5).
