CTP2000 Compression Interface Module
The CTP2000 Series compression interface module enables serial data and voice bundles to be compressed and passed through a CTP2000 platform. (See Figure 1.)
Voice bundles originating from the CTP2000 IM-8P-T1/E1, analog CTP2000 IM-4WE&M, IM-2WFXS, and IM-2WFXO modules use the CTP2000 compression module to compress the voice bundle. Voice bundles ranging from 1–24 channels on a T1 module, 1–30 channels on an E1 module, and 1–8 channels on a 4WE&M module can be bundled and connected through the compression module to compress the voice bundle and build the IP packet.
The compression module supports these compression algorithms:
MELP (2.4k)
G.729AB (8k)
G.728 (16k)
G.726 (16k)
G.726 (32k)
PMC (64k)
The module supports Mu-Law and A-Law companding, echo cancellation, silence suppression, fax/modem detection, and tone relay. You can configure the compression options when configuring the voice bundle.
