Table 3-12 Ring Node with 192 DS3 Equipment Requirements
3.8.3 Ring Application with an OTS2
Figure 3-32 depicts the TE-2020 Main Shelf in an OC-192 ring configuration with an OTS2. The main
shelf houses the OC-192 Ring interfaces and up to four OC-3, OC-12, or OC-48 interfaces. Along with the
OC-192 ring, up to eight other rings may be supported at the main shelf (4-port OC-3 or OC-12 PLMs).
The tributary shelf is fully populated with protected or unprotected facilities. The OTS2 could be popu-
lated with 4 port OC-3 or OC-12 PLMs to provide interconnection for an additional maximum 8 UPSR
rings. Likewise 2-port OC-12 PLMs (UPSR, 1+1, Unprotected) or OC-48 PLMs (UPSR, BLSR, 1+1,
Unprotected) can provide optional interfaces. This configuration requires only four rack units of space.
One tributary shelf with two LEI connections can support a combined 96 STS-1s worth of bandwidth that
can be used for transport and partially filled applications. Hairpin connections can be performed at a shelf
level without utilizing LEI bandwidth.
The OTS2 can also be equipped with optional VT-matrix equipped CCTs to support local UPSR switching
in additon to STS-1 switching.
