    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.

    TCSM3i for stand-alone installation

    In standalone installation, transmission can be implemented on ETs (E1/T1PCM), EETs (PWE) or ETPs (Ethernet).

    Can be shared with up to 30 BSCs

    TCSM3i for combined installation

    TCSM3i is mounted together with BSC3i.

    Enables optical STM-1/OC-3, PWE or A over IP connections in the A-interface towards the MGW.

    Ater interface implemented by the Hotlink cables from TCSM directly togroup switch (GSW2KB) in Master BSC.

    Combined TCSM can be shared to another BSCs (called Remote BSCs)

    Remote BSC which use the combined TCSM must connect to Master BSC(called AREMO interface), and internal semipermanent broadband must becreated in order to connect Aremo interface to Ater interface.

    TCSM3i architecture (1/2)

    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.

    Slot IDs are identical for both sections in Standalone configuration.

    Combined Installation equipping has minor differences in interface card slots. Slot ID valuesfor slots 13, 14, 26 and 27 are configured with Standalone/Combined jumper setting located

    in the cartridge. On Combi installation, CLxTG is replaced by CLAB PIU, responsible for distributing the clock

    signal generated by the BSC. SBMUX PIU is also added, used to connect the BSC GSWand the TR3E/TR3A/TR3T plug-in units as well as between the optical interface plug-in unitETS2 and the TR3E/TR3A/TR3T.

    TCSM3i configuration on RG20 (2/2) TR3T plug-in units which control and supervise ET16 plug-in units in the A interface are called masters.

    Master TR3T plug-in units are located in slots 5, 9 and 13 in every TC2C-A catridge in the TCSM3i cabinet.

    TR3T plug-in units which supervise ETIP1-A plug-in units are calledAter ETIP masters orA ETIP masters.

    A cartridge masteris a TR3T plug-in unit which controls and supervises ET16 plug-in units in the A and

    Ater interfaces. A cabinet head masteris a TR3T PIU which controls and supervises the TCSM3i cabinet clock. There is

    only one cabinet head master in the TCSM3i cabinet and it is located in slot 2 of the cabinet's first cartridge.
