Function 2133: CSU Emulation
Use the scroll keys to toggle between enabled and disabled. Default: Off. If there is no external
CSU, the CSU Emulation setting should be set to On but the remaining options should be left at the
default setting of On. When CSU emulation is enabled, the following test options will be available
and should be used only at the request of the carrier:
Test option* Description
ATT PRF Loopback test per AT&T spec 62411 for performance assessments,
sent to the carrier on ESF trunks only.
ANSI PRM Loopback test per ANSI spec T1.403 for performance assessments,
sent to the carrier on ESF trunks only.
PLB (Payload loopback.) Accepts signal from the carrier at the chip level,
puts it through the framer (de-frames and re-frames signal with data
staying the same) and sends it back to the carrier. Used to determine
whether the chip itself is functioning correctly.
LLB (Line loopback.) Sends the signal back right at the point it enters the
chip before it enters the framer. Helps determine whether the line
itself is good.
NET LLB (Network loopback.) Lets the carrier put the DLC's CSU into any of the
loopback modes.
* Test options available only when CSU emulation is set to On.
Warning: The default setting is Off for those systems using an external CSU. If there is no
external CSU, the CSU Emulation setting should be set to On but the remaining
options should be left at the default of Off. Use these other settings ONLY at the
request of your carrier or the phone system manufacturer for testing purposes.
Function 2134: Switch protocol selection
Use the scroll keys to select from the four switch options for your carrier.
• Nortel – DMS100
• AT&T/Lucent – 5ESS
• National/NI2 - Default
• Siemens - EWSD
Note: Most switches can emulate the various protocols. Please be sure to base your selection on
the protocol actually being used rather than the identity of the switch manufacturer. For ex-
ample, your central office could have a Nortel DMS100 switch but have the span configured
as NI2; in this case, you should choose the default setting of National/NI2.
