Node ID (Range1-16) on each OSIRIS ring network that it is connected to. DCC wrapping and recovery
from fiber failures is fully implemented (
TE-2020 is a full participant in the OSIRIS DCC).
NOTE: Only a single
TE-2020 is currently supported per OSIRIS ring. OSIRIS Node numbers are
of local significance with an OSIRIS only. A single
TE-2020 may use the same OSIRIS Node num-
ber on every OSIRIS ring it is connected to if required.
11.1.3 OC3/OC12 URSR Ring Support
• Currently supported on only TE-2020 Main Shelf
- Full STS1 cross-connect between MAS/OSIRIS rings
- Support for Max 8 OC3/OC12 UPSR rings
• Path Switching Support:
- STS1 Path Switching
- VT1.5 Path Switching
NOTE: Contact Turin Networks Marketing for further information on configurations supported.
Hardware and Software Requirements
• At least one OSIRIS node in each ring managed must be equipped with an NMCU CPU card
(remainder can have MCU CPU cards).
NOTE: NMCU = OSIRIS CPU with integrated LAN management port. MCU = OSIRIS CPU with-
out a LAN management port.
OSIRIS Software Requirements
• Software Version 5.9.4/5.99.4 for NMCU based OSIRIS NEs
• Software Version 3.99.2/3.9.2 for MCU based OSIRIS-NEs
IP Address Allocation Requirements
• One IP address required per TE-2020 plus one IP subnet per managed OSIRIS ring
OSIRIS to TE-2020 Fiber Connectivity
Since OSIRIS NEs have an OC-3 or OC-12 OAU (Optical Access Unit) per UPSR path while the TE-2020
has an Optical PLM per direction (e/w), each TE-2020 optical PLM must have fiber connections to both
OSIRIS OAUs.
NOTE: The OSIRIS DCC has two logical directions (termed DCC-X and DCC-Y). In order for the
OSIRIS DCC to function correctly, the X-DCC on one NE must be connected to Y-DCC on the next
in order for the DCC to operate correctly and to survive fiber failures. Figure 12-6 indicates the cor-
rect fiber layout from a
TE-2020 to an OSIRIS as follows:
NOTE: The leftmost OAU card slot in an OSIRIS system is designated OAU-A while the rightmost
OAU slot is designated OAU-B
• Xmt of OC-3/12 PLM in top TE-2020 CCT connects to OAU B Rcv on OSIRIS
