ESA limits

The following limits apply to the RLCM in ESA mode.
Limits during the ESA mode
Limits during the ESA mode for POTS lines and features are:
The system supports the three to seven digit POTS dialing plan.
The system supports one home number plan area (HNPA) code for each
RLCM.
Limits during the ESA mode for MDC lines and features are:
The system supports the MDCXLA translation selector (number of digits
in the extension number) for station-to-station calling. If the selector
does not receive data, the system uses POTS translation.
The system does not support network class of service (NCOS) for MDC
lines. Customer groups or lines are restricted to a dialing plan that is
common to every customer group.
For support during the ESA mode, the primary number of a MADN
group must be an MDC business set PDN key or a 500/2500 Set
directory number.
Note: The system does not support every MDC and POTS feature or
line.
