TraverseEdge 2020 Applications and Engineering Guide, Chapter 6: Bandwidth Management
Page 6-2 Turin Networks Release 5.0.x
A GbE's bandwidth can vary from an STS-1 to STS-1-Xv (X= 1-21) or STS-3c-Xv (X = 1-7), i.e., from 1
to 21 STS-1’s. Bidirectional connections utilize bandwidth in both directions while unidirectional connec-
tions utilize bandwidth only in the from/to direction.
When equipping a tributary shelf with PLMs, the LEI capacity may need to be taken into consideration.
The following sections are provided as examples to aid the user in determining each shelf’s PLM equip-
ment possibility.
6.5.1 TE-2020 Main Shelf
The TE-2020 Main Shelf will always house ring or terminal interconnect facilities. There may be
additional slots available for tributary interfaces depending on applications and configurations.
Various combinations of thr following PLMs may be utilized and are not covered in this table. For
example, a Main Shelf could be configured for one unprotected OC-192 and one unprotected 4-
port OC-48 and still have the upper four PLM slots to populate.
