DESCRIPTION

The DCB SPL MultiDrop Remote (SPLD) multiplexer is used in

conjunction with the SRX MultiDrop Host. The SPLD is a DCB SPL

hardware platform with optional MultiDrop firmware that allows it to

operate on multidrop analog or digital phone lines.

While similar in appearance to the SPL, the SPLD is a totally different

product designed for a different application and should be treated as

such. Some of the switches perform the same function on both units.

Some do not. Please refer to appropriate section of this manual for

SPLD switch functions.
