Voip Or Udc; Msm; Timing Connections - Cisco NCS 2006 Hardware Installation Manual

VoIP or UDC

The 8 passive inventory USB 2.0 ports on the NCS 2006 ECU-S module are labeled 1 through 4 and 7
Note
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 NCS 2006 ECU-S module
is Side A and the right side of the NCS 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 NCS 2006 shelf.
There are two VoIP or UDC ports on the NCS 2006 ECU and ECU-S 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 POE functionality is not available for the VOIP ports of ECU60-S.

MSM

The multishelf management (MSM) port is an RJ-45 port that is used to connect the NCS 2006 shelf to other
NCS 2006 or NCS 2006 shelves that are a part of the multishelf configuration. There are six MSM ports on
the NCS 2006 ECU and ECU-S 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 NCS 2006 ECU and ECU-S 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 NCS 2006 shelf. The BITS-OUT ports provide output to
external devices (other Cisco or third-party shelves) to synchronize the timing signals with the NCS 2006
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.
