1
(Off-premises Station)
1. Only PESU circuits 1 and 2, and RDSU circuits 1~4 provide Off-premises Station (OPS) capability. PESU must use OL13A or
equivalent line conditioning for OPS connection. RDSU must use OL13A or OL13B if providing –24 volt loop voltage. If
equipped with the –48 volt loop option PCB (R48S), OL13A, OL13B, or OL13C may be used for OPS connection.

2. When ordering DS-1/T1 circuits, six items must be specified:
●
The number of channels per T1 circuit, fractional increments are normally 8, 12, or 16 channels, full service is 24 channels.
Unused channels must be bit-stuffed.
●
Type of CO line assigned to each channel: Loop Start, Ground Start, Tie (Wink or Immediate Start), DID (Wink or
Immediate).
●
Frame Format Type: Super Frame (SF) or Extended Super Frame (ESF). The T1 provider normally specifies the Frame
Format to be used, either is adequate for DK424i CO digital voice lines. ESF provides a higher level of performance
monitoring, but requires trained personnel and the ESF CSU normally costs more than an SF only CSU.
●
Line Code Type: Alternate Mark Inversion (AMI) or Bipolar 8 Zero Substitution (B8ZS). The T1 provider normally
specified the Line Code to be used, either is adequate for DK424i T1 CO digital voice lines.
●
The customer may have to provide the Channel Service Unit (CSU) to interface the DK424i T1 circuit to the Telco T1
circuit. (CSUs are a Telco requirement.)
●
RDTU Network Channel Interface Codes: 04DU9-BN, 04DU9-DNZZ, 04DU9-1SN, 04DU9-1KN, 04DU9-1ZN.

3. For information on how to order ISDN PRI/BRI circuits, you should refer to the Toshiba ISDN Training CBT. ISDN circuits
may require a customer-provided CSU for PRI and/or Terminal Adapter or Network Terminal units for BRI. In U.S. CSU/TAs
must be UL-listed in the U.S. In Canada, they must be CSA certified.
