The Japanese J1 standard is very similar to the T1 standard, but differs in some details.
To support these differences easily, the following features are provided within the
FALC56:
• CRC6 generation and checking according to ITU-JT G.706
• Remote alarm handling according to ITU-JT G.704
• NTT synchronization requirements in ESF framing mode
• Pulse shaping according to JT G.704
• Receive input thresholds according to ITU-JT G.703
J1 mode is globally selected by setting RC0.SJR = 1 (see
framer initialization see
No special pulse mask setting is required, the described T1-settings also fulfill the J1
requirements.
