  • Page 12: E1 Signal Structure

    Chapter 1. Introduction 1.3 E1 signal structure The E1 line operates at a nominal rate of 2.048Mbps. The data transferred over the E1 line is transmitted transparently as a bit stream in Unframed E1 mode. E1 line signal The basic E1 line signal is coded using the Alternate Mark Inversion (AMI) or HDB3 rule.

  • Page 13: Eoe-1 Capabilities

    AMI coding. HDB3 coding. E1 framing formats The EOe-1 supports only Unframed E1 format. WAN data rates The EOe-1 supports WAN channel rates of 2.048M, 1.024M, 512K, 256K, 128K, 64K, 32K, and 16Kbps and is hardwired to a synchronous Ethernet Bridge.

  • Page 14: System Timing Considerations

    The EOe-1 E1 link receive path always operates on the receive clock. The EOe-1 recovers the receive clock from the received E1 link data signal. The source of the EOe-1 E1 link transmit clock can be selected by the user.

  • Page 15: Internal Timing

    Chapter 1. Introduction • Internal timing: The EOe-1 E1 link transmit clock is derived from the internal clock oscillator. This timing mode is necessary in point- to-point applications over leased line. In this case, one EOe-1 must use the internal oscillator while the other must operate from the recovered clock.

  • Page 16: Functional Description

    The EOe-1 is capable of performing local and remote loop back. The operator at either end of the line may test both the EOe-1 and the line in the loop back mode. The loop back is controlled by a manual push-button switch.

  • Page 17: Typical System Applications

    Chapter 1. Introduction 1.7 Typical System Applications General The EOe-1 is not capable of fractional E1 operation and should be used where only an unframed, transparent 2.048Kbps transmission is available or required. In the following application, the EOe-1 is connected in a point-to-point application.

    The power cable must be disconnected before removing or replacing fuses. Rear panel connectors The interface connectors, located on the rear panel of the EOe-1 (Refer to Figure 2.1), incorporate two BNC Coax and RJ-45 connectors. (Appendix B provides detailed information on the interface connectors).

    Chapter 2. Installation 2.6 Rack Mount Installation All Standalone/Rack Series units have the option of adding standard EIA 19" rack mount capability. Two rack mount options provide for either mounting a single unit (half space) in a rack or for mounting two units in tandem (full space).
  • Page 25 Chapter 2. Installation In order to save rack mount space, units may be mounted in tandem. Please refer to the following drawing examples for this application. Figure 2.3: Tandem Units Mounting (Exploded) Figure 2.4: Tandem Units Mounting Detail The tandem kit includes two (2) rack mount brackets, one (1) each of inner and outer central mounting brackets, twenty (20) 3x8mm self-tapping screws, and four (4) #12-24x0.5"...

    EOe-1. 3.2 Controls and Indicators All controls (push-button switches) and LED indicators are located on the EOe-1 front panel. Depress a push-button to activate (turn ON) the corresponding control. Release the push- button to deactivate (turn OFF) the control.
  • Page 28 Item Control Switch Function Local Loopbk The local loop back switch causes the local EOe-1 to loop received E1 data to its transmitter. Remote Loopbk The remote loop back switch causes the remote EOe-1 to loop received E1 data to its transmitter.

  • Page 29: Operating Procedure

    • Diagnostic loops are required. The EOe-1 is turned on when its AC power cord (or central office DC power) is connected to an AC power outlet (or the DC input connections) and the power switch is turned to the ON position.
  • Page 30 Chapter 3. Operation Refer to Chapter 4 for the operation of the front panel push- button switches. Their usage is explained under the "Loop Back Tests" on page 25. The rest of this page was left blank intentionally.

  • Page 31: Chapter 4. Test & Diagnostics

    The loop back test buttons (Local Loopbk and Remote Loopbk) and the LED indicators built into the EOe-1 allow for rapid checking of the EOe-1 and the E1 line. Before testing the operation of the data system equipment and their line circuits, ensure that all units are turned on, connected properly and are configured correctly.

  • Page 33: Local Loop Back

    This test is activated by depressing the "Local Loopbk" button. This test checks the performance of the EOe-1 and the connections between them. This test consists of looping the receive E1 signal back to the remote EOe-1 . (see Figure 4.2): Figure 4.2 Local loop back...

  • Page 34: Remote Loop Back

    This test is activated by depressing the "Remote Loopbk" push button. The test checks the performance both of the local and the remote EOe-1 units, as well as their interconnecting lines. The remote digital loop back test consists of providing a loop back at the remote EOe-1 (see Figure 4.3).
  • Page 35 Chapter 4. Test & Diagnostics Loop back test notes: Use this method to quick test a standalone unit; With the E1 timing source set to internal oscillator, connect the E1 Tx to E1 Rx with a single coaxial cable. Press the Pattern switch. The E1 Tx and Rx circuits will be tested.
  • Page 36 Chapter 4. Test & Diagnostics Most Ethernet link problems occur when trying to connect to older, legacy Ethernet equipment. Unless it can be confirmed that the connecting equipment supports auto-negotiation or what is sometimes referred to as "n-way" connections, it is recommended to disable the auto-negotiation feature and manually set the speed and duplex settings.
