DTAU Function Performance
The DTAU performance requirements are specified in Section 6 of GR-818-CORE
1
. Primary require-
ments are specified in this section. Specific requirements for DS3 HCDS access testing are specified in
GR-1402-CORE. Connection and disconnection of any T1 or T3 circuit to a TAP in the monitor configura-
tion must be hitless.
The DTAU function connects the T1 and T3 circuits transparently.
DTAU out of service testing (split modes) invokes alarm suppression for the circuit under test.
RTRV-TAP-T3 Retrieves the status of a T3 TAP
DISC-TACC Disconnects the identified TAP
R.R4.1NE.TAP.7 Acterna CENTEST (and preferably Spirent BRTU) TSC/RTU compliant TL-1
commands connect, change access mode, and disconnect any DS1 circuit trans-
ported through a TE-2020 to/from a specified T1 TAP
R.R4.1NE.TAP.8 Acterna CENTEST (and preferably Spirent BRTU) TSC/RTU compliant TL-1
commands connect, change access mode, and disconnect any DS3 circuit trans-
ported through a TE-2020 to/from a specified T3 TAP
R.R4.1NE.TAP.9 Acterna CENTEST (and preferably Spirent BRTU) TSC/RTU compliant TL-1
command to retrieve the status of a given TE-2020-based T1 TAP
R.R4.1NE.TAP.10 Acterna CENTEST (and preferably Spirent BRTU) TSC/RTU compliant TL-1
commands retrieve the status of a specified TE-2020 T3 TAP

R.R4.1NE.TAP.11 Connection and disconnection of a T1 circuit to a TAP in monitor mode is hit-
less to the T1 under test and all other active traffic in the TE-2020 element.
R.R4.1NE.TAP.12 Connection and disconnection of a T3 circuit to a TAP in monitor mode is hit-
less to the T3 under test and all other active traffic in the TE-2020 element.
R.R4.1NE.TAP.13 The T1 TAP connection to the TSC/RTU is unframed; The TE-2020 supports
transparent connection of any DS1 circuit, regardless of framing (SF/ESF/
Unframed/SLC96) to a T1 TAP
R.R4.1NE.TAP.14 The T3 TAP connection to the TSC/RTU is unframed; The TE-2020 supports
transparent connection of any DS3 circuit, regardless of framing (C-bit Parity
or M23/M13) to a T3 TAP
R.R4.1NE.TAP.15 DTAU out-of-service test states cause alarm suppression for circuit under test
