NAME
DBUSY DBUSY = 1: Disables busy mechanisms on both transmit and receive.
XYEL
RYEL
RMODE Defines the retransmission method to be used.
BECDOUBLE Provides double transmission of all MSUs in BEC. All MSU’s
ERMEN Enables the AERM and SUERM error rate monitors.
OCTEN Enables octet counting.
2/3EN
Missed MSU interrupts (CSR0<06>, MISS) are not affected by this bit.
XYEL= 0: Transmitted SINs and SIEs conform to CCITT
Red/Blue Book definitions (SF = 1 and 2 respectively). XYEL= 1:
Transmitted SINs and SIEs conform to CCITT Yellow Book defini-
tions (SF = 9 & 10 respectively).
RYEL= 0: Only CCITT Red/Blue Book definitions for received SINs
and SIEs are accepted.
RYEL= 1: Either CCITT Yellow or Red/Blue Book definitions for re-
ceived SINs and SIEs are accepted.
RMODE = 0: specifies Basic Error Recovery (BEC).
RMODE = 1: specifies Preventive Cyclic Redundancy(PCR).
including those sent during negative acknowledgement are transmit-
ted twice. If RMODE= 0 then the following definitions apply:
BECDOUBLE = 0: specifies normal BEC.
BECDOUBLE = 1: specifies BEC with doubletransmission.
NOTE: BECDOUBLE must be 0 if RMODE = 1.
ERMEN = 0: disables the AERM and SUERM.
ERMEN = 1: enables the AERM and SUERM.
OCTEN = 0: disables octet counting.
OCTEN = 1: enables octet counting.
Enables 2/3 errored FIB/BSN error monitoring.
2/3EN = 0: disables 2/3 error monitoring.
2/3EN = 1: enables 2/3 error monitoring.
ANSIT6/T7 =0: T6 & T7 timer operation complies with ITU Q.703
ANSIT6/T7 =1: T6 & T7 timer operation complies with ANSI T1.111.3
RESERVED Must be programmed with all zeroes.
