1. BSTU parameters: Loop current 25mA to 35mA. Maximum loop resistance allowed:
| • | 600ohm each without R48S1A - Class B (FCC Part 68) |
| • | 1200ohm each with R48S1A - Class C (FCC Part 68) |
| 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 circuit card (R48S), OL13A, OL13B, or OL13C may be used for OPS connection. |
| 2. | Supports one ringer per circuit. Does not support Message Waiting Lamp or OPS. |
| 3. | BSTCIU parameters: Loop current 25mA to 35mA. Maximum loop resistance allowed: |
| • | 600ohm each without R48S1A - Class B (FCC Part 68) |
| • | 1200ohm each with R48S1A - Class C (FCC Part 68) |
| • | Ring cadence: On 2 sec., Off 4 sec. (Use for Caller ID) or On 1 sec., Off 3 sec. |
5. Loop current requirements for Strata loop and ground start lines: 20 milliamperes (mA) min./120 mA max.
6. 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 CIX 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- 1 ZN. |
| 4. | For information on how to order ISDN PRI 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 Strata Net private networking. |
