Digital Recorder Interface STM-1 I/O


701308       Optical
701308-1    Electrical

  Universal Line Interface for any Digital Recorder

The module provides clock and data recovery from the high speed serial input and de-serializes the data stream for parallel interface to digital recorders, up to 16 bits wide plus parity. Playback is handled though the same module and can be performed simultaneously from the same or a second recorder. User control is implemented through two interfaces, a RS232 craft port and 10/100 Base Ethernet port. Communication setup, such as IP address and other fundamentals are handled through terminal interface via the RS232 communication port. Operation is carried out via Ethernet to the embedded webserver. Front panel indicators include indicators for basic functions such as LINE, LOCK, RECORD, PLAY and PARITY ERROR. Basic RECORD and PLAY as well as LED brightness can also be controlled from the front panel. Line interface is compliant with ITU-T G.703, G.825, G.958, Telcordia TR-NWT-00253 and ANSI T1.105.03-1994, T1.105-1994 & T1.102-1993.
Other interfaces are available for low rate PDH and Analog l/O
