The source selection is shown below where: & = the logical "AND" function, + = the logical "OR" function, and
= represents a control state.
Tx B1 Selection
The B1 Byte sent to the Tx Line is dependent on the setting of STS1 and TRERR.
When STS1 = "0" the outgoing B1 Byte will contain the contents of the Tx B1 Error Mask (149[H]). The control
TRERR is used to enable an automatic reset to all "0" of the B1 Mask. When set to "1" the B1 Error Mask will
be reset after one frame. A value of "0" will disable the automatic reset feature.
In configurations where STS1 = "1", the B1 Byte is calculated and placed in the Insert B1 Location. The calcu-
lation is Even Parity, independently performed, in parallel, over the eight bit positions of all bytes to be transmit-
ted, after scrambling is performed. The value calculated for Frame n will be placed in the B1 Byte of Frame n+1
before scrambling is performed. The calculated value in the B1 Insert Location will be Exclusive-OR gated with
the Tx B1 Error Mask prior to insertion in the transmit B1 Byte position. TRERR controls the resetting of the
mask as explained above.
Tx E1 Selection
E1 Byte selection is controlled by TRE1 (CR8; 1F8[H], Bit 5) and TXE1EXT (CR14; 1FE[H], Bit 5). The source
selection is shown below where: & = the logical "AND" function, + = the logical "OR" function, and = represents
a control state.
These selections are not available if the E1 Byte is used for in-band alarm communication. See the section "Tx
E1 Alarm Insertion," below.
