NOTES
In SC2000 installations, the SCM and modem
must be installed in the same shelf; the SRM-6
is installed in either slot of a second shelf.
In DDS and T1 applications, the SC21A/S or
SC553 DSU replaces the modem. Refer to the
corresponding manual to make rear panel
connections to those devices.
In a SC5000 shelf, install cards in any slot.
