PROPRIETARY AND CONFIDENTIAL
Table 11: Structure for Carrying Multiplexed Links
The TECT3, when enabled for SBI interconnection, will add and drop either 28
T1s or a DS3 into one of the three Synchronous Payload Envelopes, SPE1,
SPE2 or SPE3.
Tributary Numbering
Tributary numbering for T1 uses the SPE number, followed by the Tributary
number within that SPE and are numbered sequentially. Table 12 shows the T1
column numbering and relates the tributary number to the SPE column numbers
and overall SBI column structure. Numbering for DS3 follows the same naming
convention even though there is only one DS3 per SPE. SBI columns 16-18 are
unused for T1 tributaries.
