TimeProvider 5000 Expansion Shelf System
The TimeProvider 5000 Expansion Shelf system consists of a TP5000 with
Expansion versions of the IMC and I/O cards, a new output expansion shelf with
Gigabit SyncE/PTP ports, and a new output expansion shelf with E1 and
1PPS+TOD ports.
The TP 5000 Expansion Shelf system supports two IOC cards in 1+1 redundant
configuration. These two IOC cards track one or more of the time and frequency
reference inputs and provide the stable time and frequency signals that are used to
generate output synchronization signals. The 090-50331-04 version of the IMC
supports the Beidou satellite system. The 090-50301-02 chassis, 090-50315-01 I/O
module and 090-50331-02 IMC or 090-50331-04 IMC will support 1PPS+TOD
inputs.
Functionally the TimeProvider 5000 system can be thought of as a BITS or SSU in a
central office or a secondary office. It accepts time and frequency reference inputs
in multiple formats, and it provides time and frequency synchronization signals to
the network equipment in the office.
Figure 1-11 shows the physical interfaces of a typical TimeProvider 5000 Expansion
Shelf system that consists of a TP5000 and two output expansion shelves.
The TP5000 has four primary functions in the system:
