T1/E1/J1 FRAMER/LIU COMBO - ARCHITECTURE DESCRIPTION

High-Speed Multiplexed Interface
In addition to the non-multiplexed mode, the framer can interface through the backplane in a high-speed
multiplexed application, either through a bit-muxed or byte-muxed (in HMVIP or H.100) manner. In this mode,
the chip is divided into two multiplexed blocks, four channels per block. For T1, the high speed multiplexed
modes are 12.352Mbps (bit-muxed, TxSYNC is “High” during the F-bit), 16.384Mbps (bit-muxed, TxSYNC is
“High” during the F-bit), 16.384Mbps (HMVIP: byte-muxed, TxSYNC is “High” during the last 2-bits of the
previous frame and the first 2-bits of the current frame), or 16.384Mbps (H.100: byte-muxed, TxSYNC is “High”
during the last bit of the previous frame and the first bit in the current frame). For E1 mode, the only mode that
is not supported is the 12.352Mbps. The only other difference is that the F-bit (for T1 mode) becomes the first
bit of the E1 frame.
Figure 20
is a simplified block diagram of transmit bit-muxed application.
Figure 21
is a
simplified block diagram of receive bit-muxed application. Although the data is only applied to channel 4 or
channel 0, the TxSERCLK is necessary for all channels so that the transmit line rate is always equal to the T1/
E1 carrier rate.
