When you have created or modified a nailed profile in RADIUS, you must reload the
information from the RADIUS server. To request a reload of all nailed profiles (permanent
connections) from the RADIUS server, select the command Sys > Sys Diag > Upd Rem Cfg.

Spanning multichannel calls across a stack of units

If you configure multiple MAX units to form a stack, the multiple channels of an MP or MP+
call can span the units in the stack, as shown in Figure 4-4.

Call spanning with a stack configuration can be effective when:
•
•
MP/MP+ call spanning is protocol independent and works with all protocols supported by the
unit.
Note: Stacking requires any MP caller to use the MP endpoint discriminator. The same is true
of MP+. All Lucent products and most other products that support MP or MP+ use an endpoint
discriminator, but the specification for MP does not require it.
How MP/MP+ call spanning works
A stack is a group of MAX units that have the same stack information and are on the same
physical LAN. There is no master unit. The MAX units in the stack use a directed-broadcast
Ethernet packet to locate each other. Directed broadcast packets usually cannot cross a router,
so the units in a single stack must be on the same physical LAN. MAX units running in a stack

Value
Name of a profile to use if the nailed connection goes down.
Type of nailed call. Set to Nailed (1) for nailed connections.
Group numbers of the dedicated channels for the connection. You
can specify multiple groups by separating the numbers with
commas, in which case the bandwidth of the connection is an
aggregate of all specified groups. Nailed bandwidth cannot be
shared by other connections.

A MAX unit running MP+ asks for another telephone number, and has no available lines.
A rotary hunt group uses the same telephone number to access multiple units, making it
impossible to assume that the same unit that answered the original call answers a
subsequent call.
