Activation (HTU-C)
Source: Customer 1111110
(6 in 7) Signal sent in-band. HTU-C loops back the T1 data
to the customer equipment.
Activation (HTU-C)
Source: Customer 0011 1111 0001 1110/
3F1E Signal sent in-band. HTU-C loops back the T1 data
to the customer equipment.
Activation (HTU-R)
Source: Network 1111 1111 0000 0010/
FF02 Signal sent in-band. HTU-R loops back the T1 data
to the network equipment.
Activation (HTU-R)
Source: Network 1110000
(3 in 7) Signal sent in-band. HTU-R loops back the T1 data
to the network equipment.
Activation (HTU-R)
Source: Customer 1111100
(5 in 7) Signal sent in-band. HTU-R loops back the T1 data
to the customer equipment.
Activation (HTU-R)
Source: Customer 0011 1111 0000 0010/
3F02 Signal sent in-band. HTU-R loops back the T1 data
to the customer equipment.
Activation (HTU-R)
Source: Network or
Customer 1100 0111 0100 0011/
C742 Signal sent in-band. HTU-R loops back the T1 data
to the source direction. Sends 20 bit errors every 10
seconds.
Activation (HRE-1)
Source: Network or
Customer 1100 0111 0100 0001/
C741 Signal sent in-band. HRE-1 loops back the T1 data
to the source direction. Sends 10 bit errors every 20
seconds.
Activation (HRE-2)
Source: Network or
Customer 1100 0111 0101 0100/
C754 Signal sent in-band. HRE-2 loops back the T1 data
to the source direction. Sends 200 bit errors every
20 seconds.
Query (All Elements)
Source: Network 1101 0101 1101 0101/
D5D5 Signal sent in-band. Any unit that is in network
loopback injects bit errors into the data looped to
the network equipment. The element closest to the
network that is in loopback injects the errors.
• HTU-C that is in a network loopback injects
231 bit errors every 20 seconds.
• HTU-R that is in a network loopback injects
20 bit errors every 10 seconds.
• HRE-1 that is in a network loopback injects
10 bit errors every 20 seconds.
• HRE-2 that is in a network loopback injects
200 bit errors every 20 seconds.
Disable Loopback
Timeout Source:
Network 1101 0101 1101 0110/
D5D6 Signal sent in-band. Loopback Timeout is disabled
as long as any element is in loopback or armed.
Disable Span Power
Source: Network 0110 0111 0110 0111/
6767 Signal sent in-band. Span power is disabled until
this pattern is removed.
