TFRA08C13 OCTAL T1/E1 Framer
Frame Formats
D4 Frame Format
D4 superframe format consists of 12 DS1 frames. Table 8 shows the structure of the D4 superframe.
Table 8. D4 Superframe Format
1. Frame 1 is transmitted first.
2. Following ANSI T1.403, the bits are numbered 0—2315. Bit 0 is transmitted first. Bits in each DS0 time slot are numbered 1 through 8, and bit
3. The remote alarm forces bit 2 of each time slot to a 0-state when enabled. The Japanese remote alarm forces framing bit 12 (bit number
4. Signaling option none uses bit 8 for traffic data.
5. Frames 6 and 12 contain the robbed-bit signaling information in bit 8 of each voice channel, when enabled.
The receive framer uses both the F
