TCSM
A transcoder or rate adapter function is needed, because A-interface channel bit rate is 64kbit/s, but the net radio path traffic channel is at a rate of less than 16 kbit/s
Transcoding or rate adaptation function may be geographically situated at either the MSCsite or the BSS site, however the transcoder is considered to be part of the BSS.
Submultiplexing can be utilized between BSC and transcoder for maximum transmissionefficiency i.e. allocating as many as four 16 kbit/s channels to a single 64 kbit/s timeslot in the
Ater PCM Transcoding and rate adaptation

TCSM3i Capacity Evolution (RG20)Summary
The TCSM3i transcoder was introduced with the
BSS12 release
TC1C-A is a full shelf wide transcoder cartridge,
and It is used as an equipment location for TR3T,
ET16, CL3TG-UA, CLAB-UA, ETIP1-A, ETP-A and
SBMUX-A plug-in units.
Configurations in one cartridge solution support
E1/T1, optical STM-1/OC-3 and/oroptical or copper
GigE E1/T1 over IP(ETIP1-A) orA over IP(ETP-A)
interfaces.
Maximum capacity in one 5 shelfcabinet if using:
Standalone TCSM is 14400 channels forETSI
and 11400 forANSI channels with up to 30
different BSCs can be connected
Combined BSC/TCSM is 16320 . 33600
channels (single and with second cabinet) for
ETSI and 16184 . 31416 channels (single
and with second cabinet) forANSI
Summary:
The TCSM3i Transcoder was introduced with the BSS12 Release.
The extremely high channel capacity of the TCSM3i is now yet further extended with a newconfiguration setup - supporting up to 14400 traffic channels in an ETSI environment and11400 traffic channels in an ANSI environment for a stand-alone installation.
The capacity of the combined BSC / Transcoder solution remains at the market leading34000 channel level (introduced with the BSS13 Release), but the packing density hasbeen further increased, so that this can now be realised with two cabinets instead of thecurrent three.
Enhancements to the BSC connectivity have also been realised, where up to 272 differentBSCs can now be connected to a combined BSC / Transcoder solution and up to 30for standalone configurations.
A new transmission interfacing option will also be available for the A over IP function enabled via the ETP-A interface module.
Benefits for the Operator:
The following benefits are realised:
CAPEX Savings, through combining the enhanced capacity of the TCSM3i with aflexible site installation
OPEX Savings, through reduced transmission, site and O&M costs
In addition to the significant benefits of the TCSM3i for existing combined BSC / TCSMsolutions, that is, native optical A-interfaces for fast installation and clear transmission andsite cost savings, the major capacity increase enables a new flexibility in BSC / Transcodersite installations.
Moreover, a greater number of BSCs can now be served by a single transcoding entity,simplifying the network design.

The TCSM consists of a transcoder plug-in unit TR3E/TR3A/TR3T and relatedExchange Terminal (ET) units.
The actual transcoding, rate adaptation, and submultiplexing function is done inthe TR3E (Transcoder Plug-in unit ETSI, 120 channels), TR3A (Transcoder Plug-in unit ANSI, 95 channels), or the TR3T (both ETSI and ANSI).
The cartridge has two logical TR3T/interface card sections divided by CLxTG unit.
