In-Depth Information
Hardware MTPs include Cisco NM-HDV2, NM-HD-1V/2V/2VE (2800 and 3800 series routers), 2900 and 3900 with PVDM3, WS-
SVC-CMM-ACT, and WS-X6608-T1/E1:
■
For NM-HDV2 and NM-HD-1V/2V/2VE (2800 and 3800 series routers), each DSP supports 16 G.711 sessions or 6 G.729,
G.729b, or GSM sessions.
■
For 2900 and 3900 series routers with PVDM3, the PVDM3-16 supports 16 G.711 sessions, and the PVDM3-256 supports
256 G.711 sessions.
■
For WS-SVC-CMM-ACT, each DSP supports 256 G.711 sessions or 128 G.729, G.729b, or GSM sessions.
■
For WS-X6608-T1/E1, each MTP port supports 24 sessions (G.711, G.729, G.720b, or GSM).
You configure MTPs in CUCM Administration by navigating to
Media Resource, Media Termination Point
.
Depending on the type of CUCM deployment, MTP and transcoding resources might not be required.
In a single-site CUCM deployment, transcoding is not required, but MTP resources may be required if there are a large number of
H.323v1 endpoints.
In a multisite WAN deployment with centralized CUCM call processing, MTP and transcoding resources are shared between CUCMs
in the cluster at the central site using MRG/MRGLs. Placement of MTP and transcoding resources depends on where the endpoints
that require these resources are located. Careful placement can ensure that media streams do not unnecessarily transit the WAN.
In a multisite WAN deployment with distributed CUCM call processing, MTP and transcoding resources are shared between CUCMs
in the clusters using MRG/MRGLs. The use of MTP and transcoding resources is avoided and is used only when an application
supports G.711 or there are H.323v1 endpoints.
