Timing Connections - Cisco ONS 15454 M6 Installation Manual

VoIP or UDC
Note The 8 passive inventory USB 2.0 ports on the NCS 2006 ECU-S module are labeled 1 through 4 and 7 through
10. The USB 3.0 port on the left of the faceplate is detected as A5. The USB 3.0 port on the left of the faceplate
is detected as B5. However, CTC represents the passive inventory ports as USBP_SIDE_PORT, where SIDE
can be A or B, and PORT can be any value from 1 to 5. For example, Port 1 on the left side of the ECU-S
module is represented as USBP_A_1 and Port 1 on the right side of the NCS 2006 ECU-S module is represented
as USBP_B_ 1. The left side of the ONS 15454 M6 2006 ECU-S module is Side A and the right side of the
ONS 15454 M6 2006 ECU-S module is Side B.
VoIP or UDC
VoIP or UDC is an RJ45 port that can be configured to support UDC or VoIP service on an ONS 15454 M6
shelf. There are two VoIP or UDC ports on the ECU modules. The VoIP or UDC port on the left side is
connected to the TNC or TNCE card in Slot 1 and the port on the right side is connected to the TNC or TNCE
card in Slot 8. The VoIP or UDC port also supports Power over Ethernet for connecting VoIP equipments.
Note Power over Ethernet functionality is not available on ECU-60V.
MSM
The multishelf management (MSM) port is an RJ-45 port that is used to connect the ONS 15454 M6 shelf to
other ONS 15454 or ONS 15454 M6 shelves that are a part of the multishelf configuration. There are six
MSM ports on the ECU modules—three ports on the left side and three ports on the right side. The MSM
ports on the left side correspond to the TNC/TNCE/TSC/TSCE card in Slot 1, and those on the right side
correspond to the TNC/TNCE/TSC/TSCE card in Slot 8. Three MSM ports are used as working ports, and
the remaining three are used as standby ports.

Timing Connections

The ECU modules have four Building Integrated Timing Supply (BITS) connections that support both ETSI
and ANSI connections. There are two BITS-IN and two BITS-OUT connections that can either be SMB
connectors for ETSI connection or wire-wrap pins for ANSI connection, based on customer requirements.
The BITS-IN ports receive input from third-party external sources called Synchronization Supply Unit (SSU)
to synchronize the timing of the ONS 15454 M6 shelf. The BITS-OUT ports provide output to external devices
(other Cisco or third-party shelves) to synchronize the timing signals with the ONS 15454 M6 shelf.
Note For timing connection, use 100 ohm shielded BITS clock cable pair #22 or #24 AWG (0.51 mm² [0.020 inch]
or 0.64 mm² [0.0252 inch]), twisted-pair T1-type.
Note See Telcordia SR-NWT-002224 for rules about provisioning timing references.
