Multiframe Sync Pulse (TxMSYNCn) / Transmit Input Clock
(TxINCLKn)
The exact function of these pins depends on the mode of opera-
tion selected, as described below.
DS1/E1 Base Rate Mode (1.544MHz/2.048MHz) - TxMSYNCn
In this mode, these pins are used to indicate the multi-frame
boundary within an outbound DS1/E1 frame.
In DS1 ESF mode, TxMSYNCn repeats every 3ms.
In DS1 SF mode, TxMSYNCn repeats every 1.5ms.
In E1 mode, TxMSYNCn repeats every 2ms.
If TxMSYNCn is configured as an input, TxMSYNCn must pulse
"High" for one period of TxSERCLK during the first bit of an out-
bound DS1/E1 multi-frame. It is imperative that the TxMSYNC
input signal be synchronized with the TxSERCLK input signal.
If TxMSYNCn is configured as an output, the transmit section of
the T1/E1 framer will output and pulse TxMSYNC "High" for one
period of TxSERCLK during the first bit of an outbound DS1/E1
frame.
DS1/E1 High-Speed Backplane Modes* - (TxINCLKn as INPUT
ONLY)
In this mode, TxINCLK0 must be used as the high-speed input
clock pin for the backplane interface to latch in high-speed or mul-
tiplexed data on the TxSERn pin. The frequency of TxINCLK0 is
presented in the table below.

*High-speed backplane modes include (For T1/E1)
2.048MVIP, 4.096MHz, 8.192MHz, 16.384MHz HMVIP,
H.100, Bit-multiplexed modes, and (For T1 only)
12.352MHz Bit-multiplexed mode.
In DS1 high-speed modes, the DS-0 data is mapped into
an E1 frame by ignoring every fourth time slot (don’t
care).
These 8 pins are internally pulled “Low” for each
channel.
