Page 5: Functional Description
O3-4D1L3 U2 1631, Issue 4, October 2009 3. FUNCTIONAL DESCRIPTION Up to four DS1 circuits are combined into a single OC3 signal by using VT1.5 and STS-1 mapping; DS1 numbers 1, 2, 3, and 4 are mapped into STS-1 VT1.5 #1 positions 1, 2, 3, and 4, respectively. -
Page 6: Ds1 Circuitry
B. DS1 Circuitry Each DS1 is provisioned for alternate mark inversion (AMI) or B8ZS line coding. Superframe, extended superframe, or unframed formats are supported. Each DS1 pulse template meets ANSI T1.102. Each DS1 port is provisioned for digital signal cross-connect (DSX-1) type interface (short haul), with line build-outs (LBOs) appropriate to service line lengths from 0 to 655 feet as well as 0, 7.5, or 15 dB. - Page 7 O3-4D1L3 U2 1631, Issue 4, October 2009 Table 3.

Page 9: Installation
O3-4D1L3 U2 1631, Issue 4, October 2009 4. INSTALLATION DANGER The O3-4D1L3 employs Class 1 laser products. To avoid injury, do not look directly into the optical transceiver or into the fiber cable. Note that the light is invisible; the optical signal cannot be detected by the eye. -
Page 10: Controls And Indicators
O3-4D1L3 U2 1631, Issue 4, October 2009 A. Controls and Indicators Front Panel The front panel of the O3-4D1L3 provides connection to the OC3 and DS1 signals as well as the craft port. LEDs show OC3, DS1, and UNIT status. A 4-position DIP switch enables or disables each DS1. - Page 11 O3-4D1L3 U2 1631, Issue 4, October 2009 Table 6.

DS1 Loopbacks The O3-4D1L3 can recognize in-band and ESF data link loopback codes as shown in Figure 8. To respond to DS1 loopbacks, the O3-4D1L3 must be provisioned as an NT (CPE-side) unit (LT is default), have its loopbacks enabled (disabled is default), and be provisioned for either ESF (default) or SF operation.
-
Page 20: Manual Loopbacks
O3-4D1L3 U2 1631, Issue 4, October 2009 During a loopback, an alarm indication signal is sent to the DS1 Tip1/Ring1 (receive) pair. However, if the unit receives (from the OC3 fiber link) an AIS signal in the DS1 circuit being looped back, the O3-4D1L3 loopback will be deactivated to prevent the AIS from being transmitted back into the OC3 fiber link. -
