1. Only RDSU ckts. 1~4 provide Off-premises Station (OPS) ability. 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. Loop current requirements for Strata loop and ground start lines: 20 milliamperes (mA) min./120 mA max.
3. 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.
• CO line types 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 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 T1 CO digital voice lines.
• The customer may have to provide the Channel Service Unit (CSU) to interface the CTX 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.
4. 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.
5. RPTU2 is required for QSIG private networking.
