Parameter
Mediant 1000 Gateway & E-SBC | User's Manual
Description
Determines the format of the RTP header for VBR coders.
■ [0] = (Default) Payload only (no header, TOC, or m-
factor) - similar to RFC 3558 Header Free format.
■ [1] = Supports RFC 2658 - 1 byte for interleaving
header (always 0), TOC, no m-factor.
■ [2] = Payload including TOC only, allow m-factor.
■ [3] = RFC 3558 Interleave/Bundled format.
Defines the required number of silence frames at the
beginning of each silence period when using the VBR
coder silence suppression.
The range is 0 to 255. The default is 1.
Defines the AMR payload format type.
■ [0] Bandwidth Efficient
■ [1] Octet Aligned (default)
Note: The AMR payload type can also be configured per
Coder Group (see Configuring Coder
Group configuration overrides the parameter.
Determines the payload format of the AMR header.
■ [0] = Non-standard multiple frames packing in a single
RTP frame. Each frame has a CMR and TOC header.
■ [1] = AMR frame according to RFC 3267 bundling.
■ [2] = AMR frame according to RFC 3267 interleaving.
■ [3] = AMR is passed using the AMR IF2 format.
Note: Bandwidth Efficient mode is not supported; the
mode is always Octet-aligned.
Determines the DSP template used by the device. Each
DSP template supports specific coders, channel
capacity, and features.
The default is DSP Template 0.
You can load different DSP templates to analog and digital
modules using the syntax
DSPVersionTemplateNumber=xy
where:
■ x = 0 or 1 for DSP templates of analog modules
■ y = 0 to 5 for DSP templates of digital and MPM
modules
Note:
■ For the parameter to take effect, a device reset is
required.
■ For a list of supported DSP templates, see
Capacity.
Defines the number (20 msec) of coder payloads used to
generate a fax/modem bypass packet.
