• Extension Step 960 ETSI / 760 ANSI

• All TCSM2 features available

• Added enhanced pool options


Training Material

TCSM3i support in BSC - Benefits

• TCSM3i has over 12 times more capacity compared to current TCSM2 • High capacity BSC3i_2000 allows up to 2000 TRX configuration

• ~99TCSM units needed• ~12 TCSM2 cabinets• ~1 TCSM3i cabinet

• Redesigned hardware makes it more compact • Instead of several Plug-In Units one transcoder based on TCSM3i

HW technology consists from one Plug-In Unit.• TCSM3i cabined is based on M98 mechanic

• More flexible pool usage in A-interface• All-in-one circuit pools

• One TCSM3i functional unit can handle maximum four TC-PCM on A interface. (120 FR circuits).

• TCSM3i cabined is based on M98 mechanic


Training Material

Comparison between Nokia TCSM2 and TCSM3i

TCSM2

• Same platform – DX 200 – as in use with Nokia GSM/EDGE BSC2i

• Mechanics: M92• Capacity up to 960E/760A• Capacity extension step 120E/95A• Footprint 0.4 m2 • Power consumption 0.6 kW• Support for A-interface pools:

- Six different DSP SW versions- The memory consumption of AMR codec modes cause the fact that TCSM2 can support simultaneously only AMR related coding (pool 23)

TCSM3i

• Same platform – DX 200 – as in use with Nokia GSM/EDGE BSC3i

• Mechanics: M98• Capacity up to 11520E/9120A *• Capacity extension step 960E/760A *• Footprint 0.72 m2 • Power consumption 3.0 kW• Support for A-interface pools:

- Only one DSP SW version- New pools introduced: Pool 28&32- All pools as with TCSM2 supported from day one, except Pool 2 HR only

(Note! HR support is included in other pools: 3, 7, 10, 13, 20, 21, 22, 28, 32)

*) In combined BSC3i/TCSM3i installation:11358 ch ETSI in steps of 960/933 ch11424 ch ANSI in steps of 952 ch
