When finished configuring the T1 port diagnostics parameters,
enter X to return to the Diagnostics Menu.
NOTE: To do an LLB BOP or a PLB BOP to the far-end, set the far-end
“Network Initiated Loop” option to “Yes.”

Menu
Enter D from the Diagnostics Menu, Figure 3-18, to access the
Data Port Diagnostics Menu. This menu activates or deactivates
loops from the data equipment to the DPRI data port and back to
the data equipment, and from the network to the data port and
back to the network.
55 Octet: The Daly 55 octet pattern tests circuits for line card and timing
recovery. By rapidly transitioning from a long sequence of low density octets
to high density octets, the circuit is stress tested. Following is a binary
representation of the 55 Octet stress pattern:

All 1s: This pattern is composed entirely of framed ones (11111111). It
stresses circuits by maximizing power consumption.
An Send Line Loopback Bit-Oriented Protocol (LLB BOP): This option uses FDL
loopbacks to test the T1 from the near-end toward the far-end.
1) DEACTIVATE
2) ACTIVATE
Bn Send Payload Loopback Bit-Oriented Protocol (PLB BOP): This option uses FDL
loopbacks to test the CSU at the far-end circuit from the near-end.
1) DEACTIVATE
2) ACTIVATE
En Reset Test Counter: This option resets the test counter to 0. The counter is
automatically reset when changing patterns.
X Exit the T1 Port Diagnostics Menu—Returns the screen to the Diagnostics
Menu, Figure 3-18, Table 3-16.
