TDM/Flex Error Messages
Message
Condition Action
All Async >Aggr All ports of the TDM/Flex are configured
for asynchronous operation and their
combined corresponding synchronous
rate exceeds the value for the DSU, DBM,
or ExtBU Rate(Kbps) configuration option.
If all ports are assigned to asynchronous
operation, the sum of the corresponding
synchronous port speeds must be
less
than
the value of the DSU, DBM, or
ExtBU rate.
You can correct the problem in one of two
ways:
1. Set the Rate(Kbps) of the DSU, DBM,
or ExtBU to a higher value.
2. Lower the port speeds of the DSU,
DBM, or ExtBU in the PrtSp
configuration submenu.
Async Undspeed An attempt was made to run an TDM/Flex
asynchronous port at underspeed.
A port configured for asynchronous
operation
cannot
be configured to run
underspeed.
Choose a synchronous port and configure
it for underspeed via the appropriate path
(DSU or DBM) in the PrtSp configuration
submenu.
DBM Aggreg Exceeded
DSU Aggreg Exceeded
ExtBU Agg Exceed
The sum of the TDM/Flex port speeds is
greater than
the value for the DSU, DBM,
or ExtBU Rate(Kbps) configuration option.
You can correct the problem in one of two
ways:
1. Set the Rate(Kbps) of the DSU, DBM,
or ExtBU to a higher value.
2. Lower the DSU, DBM, or ExtBU port
speeds via the appropriate path (DSU
or DBM) in the PrtSp configuration
sub-menu.
DSD Speeds diff Not all of the TDM/Flex ports in the
digital-sharing group are set to the same
speed.
Set all of the ports in the digital-sharing
group to the same speed via the
appropriate path (DSU or DBM) in the
PrtSp configuration submenu.
DSD Wrong RTS One or more TDM/Flex ports in a
digital-sharing group with DSD port
control have an incorrect RTS Control
setting.
Each port in a digital-sharing group
configured for contention
must
have
its
RTS Control configuration option set to
DTE (RTS Cntrl: DTE).
Set RTS Cntrl to DTE for all ports in the
digital-sharing group via the appropriate
paths (Prt1 and Prt2) in the
MUX
configuration submenu.
Ext Time undspd The TDM/Flex port selected as the source
of external timing (TxClkSource is set to
the port specified in the DSU (or ExtBU)
and/or DBM configuration submenu) is
also an underspeed port.
A port
cannot
be the source of external
timing and also run underspeed.
Correct the problem in one of two ways:
1. Configure another synchronous port as
underspeed via the appropriate path
(DSU or DBM) in the PrtSp
configuration submenu.
2. Configure the other port to provide
external timing.
Incmpt Diag mode Mixed diagnostic type is not compatible
with point-to-point operation.
Select another diagnostic type via the
Diagnostic DSU, DBM, or ExtBU option
set.
Inval lowest Prt DCE (the first port on TDM/Flex) was
previously selected as the second port in
a digital-sharing group.
Select 1 as the first port for the
digital-sharing group via the MUX Setup
path of the MUX submenu.
