Main Features
  • CTP2000 Main Clock Card
Clock interface modules provide clock distribution between modules when the backplane is in use by voice applications. This is accomplished through a “hub-and-spoke” configuration composed of a main module (CTP-CLK-Main) and a spoke module (CTP-CLK-Spoke). Clock main modules and clock spoke modules allow more clock input types in the CTP2000 chassis and provide the capability for clock distribution when both serial modules and voice modules are installed in the same CTP2000 chassis. The main, or hub, module accepts a node reference and repeats it to all RJ-45 connectors. There are no configurable options for the clock module. Main modules and spoke modules are not hot-swappable. When installing, nonvoice modules and voice modules can be installed in any slot. Main RTMs must be installed in slot 0 behind either a serial or T1/E1 card. Spoke RTMs must be installed behind serial cards and the lowest-numbered T1/E1 slot. If a T1/E1 card is installed in slot 0, a spoke RTM is not needed behind any T1/E1 cards. They will synchronize to the H.100 clock. For systems with only nonvoice boards (serial or T1/E1 card), only a main RTM is needed for external node reference input. Compatible with the CTP2000 product line.
