8 Channel T1/E1 Converter -
8 Channel T1/E1 Converter/ECL/LVDS (RS422/LVDS/ECL OUT) 701098, 701098-1

Line termination with Data/Clock extraction, convert Data/Clock streams to AMI line output and generate test patterns for either output

The 8 Channel Converter combines 4 channels that are identical to those of the PN 701057 8 Channel Interface, but includes board jumpers to allow DATA inversion. In addition, there are 4 channels that accept DATA and CLOCK input at RS422 levels and generate a bipolar AMI output, which can be encoded B6ZS, B8ZS or HDB3. Front panel controls include T1/E1 selection and ENCODE/AMI (transparent) settings for each channel. DATA and CLOCK activity are indicated by red LEDs on the front panel. The input rate is selected on the rear panel for T1 or E1 input rates.

This unit also contains a Test Pattern Generator which is controlled by rear panel switches for each set of 4 channels. When the tester is turned on, the first channel of each section is no longer available for signal input since it is generating tester output. R3, R7 and R15 test patterns are selected by on-board jumpers. CLOCK can also be inverted by on-board jumper.

701098-1 has ECL option
