Single Serial Interface Unit (RSSU)
The RSSU contains one RS-232 serial port for connecting an SMDI, SMIS processor, DKAdmin/
DKBackup PC or external modem.
The RSSU provides a cost-effective alternative to the PIOU or PIOUS when only one other serial
I/O port is needed, or when the other features of the PIOU or PIOUS are not required. The RSSU
has a fixed speed of 1200 bps. It does not support SMDR, or the IMDU or RMDS modems.
DK40i – one optional RSSU maintenance interface PCB can be used for connecting a
maintenance PC or external modem (local or remote) to the DK40i.
DK424 – a maximum of three RSSU cards can be supported per DK424.

2. Maintenance modem, ACD/SMIS, Insight DK, Voice Mail, SMDI and DKAdmin PC Interface each require a separate TTY
output. PIOU, PIOUS, and RSSU provide one TTY output each. RSIU with RSIS PCBs provides up to four TTY outputs.
3. SMDR output will function simultaneously on the same PIOU or PIOUS with one of the following: DKAdmin, remote
modem, SMIS for ACD, Insight DK, or SMDI features.
