Line Modules

Line modules (LMs) act as frame forwarding engines for the physical interfaces (the
IOAs) and process data from different types of network connections. For information
about available line modules, and which SRP modules support specific line modules,
see the E120 and E320 Module Guide.
Figure 7 on page 12 shows a representative line module. For details about installing
line modules, see "Installing Modules" on page 27.
Disable accounting and, when there is no subscriber login or logout activity,
hot-swap SRP IOA.
Increase the timeout value of the RADIUS server configured depending on the
time used for IOA replacement. The maximum timeout value is 1000 seconds.
