LOOPBACK AND CONTROL CODES

FUNCTION CODE RESPONSE

ARM (in-band) 11000 (binary) H2TU-C and H2R will arm and the H2TU-R will loop-up toward the network

ARM (ESF Data Link) FF48 (hex) or 1111 1111

0100 1000 (binary) sent H2TU-C and H2R will arm and the H2TU-R will loop-up toward the network in the Facility Data Link H2TU-R will only loop if the NIU option is enabled

Disarm (in-band) 11100 (binary) All units are removed from the armed state and loopbacks will be released

Disarm (ESF Data Link) FF24 (hex) or 1111 1111

0010 0100 (binary) sent in All units are removed from the armed state and loopbacks will be released the Facility Data Link

H2TU-C Network Loop-Up

D3D3 (hex) or If received while in an armed state, the H2TU-C will loop toward the network, 1101 0011 1101 0011 transmit 2 seconds of AIS(all 1s) followed by 5 seconds of loop code (D3 hex)

(binary) and then 231 logic errors will be injected toward the network. The logic errors

will continue to be sent in 231 bit error bursts every 20 seconds as long as the pattern continues to be detected by the H2TU-C. When the pattern is removed, the unit will remain in loopback.

Loopdown w/out 9393 (hex) or Automatically releases without disarming any H2TU-C and H2R that may be in disarming

1001 0011 1001 0011 (binary) loopback toward the network.

Loopback Query

D5D5 (hex) or Allows one to query the devices at any given time to determine whether any 1101 0101 1101 0101 (binary) units are in loopback. If D5 hex is received while in a loopback state, the unit in

question will transmit the logic error count toward the network using the same methodology as identified in each of the loop-up descriptions (231 BE = H2TU-C, 10 BE = H2R1, 200 BE = H2R2 and 20 BE = H2TU-R).

Query Loop Parameters DBDB If the units are armed, and the H2TU-C is in network loopback, errors are

(1101 1011 1101 1011) injected into the DSX-1 signal upon detection of the query loop parameters

pattern. As long as a pattern continues to be sent, errors are injected again every 20 seconds. The number of errors injected each time depends on the current status of signal quality and pulse attenuation parameters on each loop. 111 errors are injected if all HDSL receiver [points (H2TU-C LP1/LP2, H2R #1 NET LP1/LP2, H2R #1 CST LP1/LP2, H2R #2 NET LP1/LP2, H2R #2 CST LP1/LP2, and H2TU-R LP1/LP2) indicate pulse attenuation is 30 dB or lower and signal quality (margin) is 6 dB or higher. 11 errors at a time are injected if any of the 12 receiver points indicate pulse attenuation is greater than 30 dB and/or signal quality (margin) is less than 6 dB.

Loopback Time-Out D5D6 (hex) or If received during the armed state and prior to loopback initiation, the loopback Override

1, 3

1101 0101 1101 0110 timeout override feature will automatically disable loopback timeout, i.e., the (binary) loopback will not timeout after the 120 minute default period. As long as the

units remain armed, the timeout will remain disabled. When the units are disarmed, the loopback timeout will once again return to the default value.

Span Power Disable

1, 3

6767 (hex) or If received during an armed state (must not be in loopback), the H2TU-C will remove 0110 0111 0110 0111 (binary) span power toward the line. As long as the pattern is received, the span power will

remain disabled. Once the pattern is no longer received, the H2TU-C will reactivate span power. All units will then re-train and return to the disarmed state.

H2R1 Network Loop-up1C741 If an H2R is present and units armed, the H2R will loop up toward network, 2

(1100 0111 0100 0001) seconds of AIS (all 1s) will be sent, 5 seconds of data will pass, and then 10 bit

errors will be injected into the DSX-1 signal. As long as the pattern continues to be sent, 10 errors will be injected every 20 seconds. When the pattern is removed, the unit will remain in loopback. If the pattern is reinstated, the injection of 10 bit errors will resume at 20-second intervals.

H2TU-R Loop-up

C742 ESF facility Datalink: ESF only; when sent from the network, an H2TU-R (1100 0111 0100 0010) network loopback is activated and a 20-bit error confirmation is sent. When

sent from the customer, an H2TU-R customer loopback is activated with a 20-bit error confirmation.

Units must be armed with 11000b or FF48h before this code will work.

In order to behave like an NIU, the H2TU-R will not loop down from the network side with 9393h.

This code will be detected only if the units are armed AND there are NO loopbacks active.

NOTE: All codes listed above must be sent for a minimum of 5 seconds in order for them to be detected and acted

upon.

*If NIU is enabled, then the H2TU-R can be in network loopback when the H2TU-C or H2R loop-up codes are sent.

ENHANCED PSD CARD EDGE PIN ASSIGNMENTS

The Enhanced PSD 239 H2R , P/N 1221045L2, must be used in conjunction with the Enhanced PSD T200 H2TU-R, P/N 1222026L9. This H2R will not function with any other H2TU-Rs. The Enhanced PSD T200 H2TU-R will function with all versions of the ADTRAN H2R, but the enhanced spectral performance will only be achieved using the Enhanced PSD 239 H2R.
