SPE Column

The TEMAP-84 when enabled for SBI interconnection will add and drop either 28

T1s, 21 E1s, a DS3 or an E3 into each of the three Synchronous Payload

Envelopes, SPE1, SPE2 or SPE3. Each SPE is independent of the others.

When T1 or E1 tributaries are sourced from the telecom bus via VT1.5, TU11,

VT2 or TU12 mappings, the TEMAP-84 also supports a mix of transparent virtual

tributaries with T1s and E1s. A restriction to this are that only VT1.5s, TU11s and

T1s can be mixed together or VT2s, TU12s and E1s can be mixed together.

Another restriction is that the telecom bus and SBI bus must run from the same

clock with a fixed framing offset, ie. SREFCLK and LREFCLK are externally

connected.

Tributary Numbering

Tributary numbering for T1 and E1 uses the SPE number, followed by the

Tributary number within that SPE and are numbered sequentially. Table 21 and

Table 22 show the T1 and E1 column numbering and relates the tributary

number to the SPE column numbers and overall SBI column structure.

Numbering for DS3 or E3 follows the same naming convention even though

there is only one DS3 or E3 per SPE. TVT1.5s and TVT2s follow the same

numbering conventions as T1 and E1 tributaries respectively. SBI columns 16-18

are unused for T1, E1, TVT1.5 and TVT2 tributaries.
