1. Only PESU circuits 1 and 2, and RDSU circuits 1 - 4 provide
off-premises-station (OPS) capability, All circuits
on PSTU, RSTU, provide OPS. PSTUIPESU must use OL 13A or equivalent line conditioning for OPS
connection. RSTU and RDSU must use OL 13A or OL 138 if providing -24 volt loop voltage; or, if equipped
with the -48 volt loop option PCB (R48S), OL 13A, OL 13B, or OL 13C may be used for OPS connection.

2. When ordering DS-IfTl circuits, six items must be specified:
a. The number of channels per TI circuit, fractional increments are normally 8, 12, or 16 channels, full
service is 24 channels. Unused channels must be bit-stuffed.
b. The type of CO line assigned to each channel: loop start, ground start, tie (Wink or immediate Start), DID
(Wink or Immediate).
c. Frame Format Type: Super Frame (SF) or Extended Super Frame (ESF). The Tl provider normally
specifies the Frame Format to be used, either is adequate for DK280 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.
d. Line Code Type: Alternate Mark Inversion (AMI) or Bipolar 8 Zero Substitution (BSZS). The Tl provider
normally specifies the Line Code to be used, either is adequate for DK280 Tl CO digital voice lines.
e. The customer must provide the Channel Service Unit (CSU) to interface the DK280 TI circuit to the Telco
Ti circuit. (CSUs are a Telco requirement.)
f. RDTU Network Channel Interface Codes: 04DU9-BN, 04DU9-DN, 04DU9-ISN, 04DU9-IKN, 04DU9-IZN.
