SPIRENT DLS-5A02 V2 AUTOMATIC NTT NCS NETWORK CLOCK SUPPLY RJ-45 400HZ BNC

Spirent DLS 5A02 NTT NCS Network Clock Supply The DLS 5A02, which produces an exact duplicate of the NTT clock, offers the clock with all the Bipolar Violations needed to synchronize network access equipment. It keeps a 10 ppm accuracy and has four outputs.

This unit has the following features:

• 3 RJ-45 connectors with the NTT network clocking, one for the ATU-C and two for each of two DLS Systems DLS 5102 (noise and impairments simulator) units that can be used with the system (one for each end of the connection).
• 1 BNC with a 400 Hz TTL synchronization output. 400 Hz is the base repetition frequency for TCM ISDN. The TTL output can be used to trigger oscilloscopes or other test equipment.
• There are no controls on the DLS 5A02. Once it is connected and the power switched on, operation is automatic.
