DS3 Interfaces DS3 : 44.736 MHz +/- 20 ppm DSX-3, monitor or terminate levels, B3ZS, 75 ohms, BNC Auxiliary Interfaces Frame Capture Trigger: TTL level input, BNC, 1 Kohm to +5V. Low level activates trigger. Bit Error : TTL level output, BNC, 50 ohms, High level during bit error on selected payload, DS1 or DS3 input. B3 Error : TTL level output, BNC, 50 ohms. High level 12 us pulse if any B3 errors are detected on the selected STS1 during a frame. TOH/POH Monitor TTL level output 50 pin monitor port for Transport and Path Overhead bytes. Parallel Data is valid on the rising edge of the data valid signal. The sync signal indicates the first row in the column. Each of the three TOH and POH columns have an 8-bit data port. The Pin assignments are : TOH Data Valid - pin 18 TOH Sync - pin 20 POH Data Valid - pin 19 POH Sync - pin 21 Ground pins are 17 and 42 through 46 C-10 8/15/95
Frame Detection STS1 : Detection based on Al, A2. STS3 : Detection based on Al, A2, A2. STS12 : Detection based on Al, A2, A2. Parity Detection STS1 : B1, B2, and B3 are generated from the incoming signal and compared with corresponding bytes in succeeding frames in accordance with GR-253-CORE. DS3 (Payload or Input) : M13 or C-bit frame parity is detected, compared, and stored. STS3 : B1 parity is detected, compared, and stored. B2 and B3 parity is detected, compared, and stored on a selected STS1. VT1.5 (Floating VT) : BIP-2 is detected as defined in GR-253-CORE. DS1 (Payload or Input) : CRC-6 errors are detected and stored. Section Measurements B1 Coding Errors : Total, rate, ES's, %EFS's SEFS : Total SES's : Total, for x or more CV's or OOF (x=9 for STS1 rate, x=16 for OC3 rate, x=63 for OC12 rate). Al, A2 pattern errors, OOF Line Measurements B2 Coding Errors : Total, Rate, ES's, %EFS's SES's : Total, for x or more CV's or OOF (x=12 for STS1 rate, x=32 for OC3 rate, x=124 for OC12 rate). LOP, FERF, Pointer out-of-range, APS byte failure, Invalid K1 STS Path Measurements B3 : Total, Rate, ES's, %EFS's SES's: Total, for 9 or more CV's or OOF AIS, Yellow, FEBE Selectable STS1 of STS3 or STS12 (option) C- 1 1 8/15/95
