Frequently Asked Questions (FAQ) about the 16E1 + 4xEthernet PDH Multiplexer:

• Q1: What is PDH and why would I use this multiplexer?

  A: PDH (Plesiochronous Digital Hierarchy) is a technology used to transport multiple E1 (or T1) circuits, which are common in traditional telecommunications. This multiplexer allows you to transmit up to 16 E1 signals along with 4 Fast Ethernet signals over a single fiber optic pair, saving fiber resources and enabling the integration of legacy TDM services with modern packet-based networks.

• Q2: What is the maximum distance this multiplexer can transmit data?

  A: The standard model supports transmission up to 20km over dual singlemode fiber. We also offer models with extended reach capabilities, such as 40km, 60km, 80km, 100km, and 120km. Please specify your distance requirement when requesting a quote.

• Q3: How does the Ethernet sharing work across the 4 ports?

  A: The four 10/100M Ethernet ports share a total combined bandwidth of 100Mbps. The device supports auto-negotiation and can handle VLAN-tagged traffic, allowing for logical separation and prioritization if needed.

• Q4: What is an “orderwire phone” used for?

  A: The integrated orderwire phone (RJ11 port) allows technicians at either end of the fiber link to connect a standard telephone set and communicate directly. This is extremely useful during installation, troubleshooting, or routine maintenance without needing a separate communication channel.

• Q5: What does “ALS Function” mean?

  A: ALS stands for Automatic Laser Shutdown. It’s a safety feature that automatically turns off the optical laser transmitter if the fiber optic cable is disconnected or broken, preventing potential eye damage from invisible laser light.

• Q6: Is SNMP management included by default?

  A: SNMP (Simple Network Management Protocol) for remote monitoring and management is typically an optional feature. If you require SNMP capabilities, please specify this when ordering or requesting a quote so we can provide the appropriate model.

• Q7: What E1 interface standards does this device support?

  A: It supports ITU-T G.703 for the E1 interface, using HDB3 line coding, and is compliant with G.704 for framing and G.823 for jitter performance. Connectors can be BNC (75 ohm unbalanced) or RJ45 (120 ohm balanced) depending on the configuration.

• Q8: Can I use this multiplexer with different fiber connector types?

  A: The standard fiber optic connector is FC/PC. If you require other connector types like SC/PC or ST/PC, please let us know your requirements, and we can check for available options.

• Q9: What power supply options are available?

  A: The unit can be configured with AC 220V (wide range 165V~265V), DC -48V (wide range -36V~-72V), or an optional AC+DC dual redundant power supply for enhanced reliability.

Yes, this equipment warrants installation guidance.

Step-by-Step Installation Guide for Your PDH Fiber Optic Multiplexer:

Proper installation is key to the reliable performance of your 16E1 + 4xEthernet PDH Multiplexer. Follow these steps: (Always ensure you are electrostatically discharged before handling equipment and fiber optics.)

1. Unpacking and Inspection:
   • Carefully unpack the multiplexer and all accessories (power cord, rack-mount ears, user manual if provided).
   • Inspect for any physical damage sustained during shipping. Report any damage immediately.
2. Rack Mounting (19-inch 1U):
   • Attach the provided rack-mount ears to the sides of the multiplexer chassis using the supplied screws.
   • Securely install the multiplexer into a standard 19-inch equipment rack, ensuring adequate ventilation around the unit.
3. Grounding:
   • Connect the chassis grounding terminal (if present) to a reliable earth ground point in your rack or facility for safety and optimal performance.
4. Power Connection:
   • Verify that your power source matches the type indicated on the multiplexer (e.g., AC 220V or DC -48V).
   • Connect the appropriate power cord to the multiplexer’s power input socket and then to your power source.
   • If using a dual power supply model, connect both power sources.
   • Turn on the power. Check the power LED indicator on the front panel.
5. Fiber Optic Connections:
   • Crucial: Before connecting, ensure all fiber optic connectors (on the multiplexer and your patch cords) are clean. Use appropriate fiber optic cleaning tools.
   • Identify the transmit (TX) and receive (RX) optical ports on the multiplexer. For dual fiber systems, ensure TX from one unit connects to RX on the remote unit, and vice-versa.
   • Connect your singlemode dual fiber patch cords (with the correct connectors, e.g., FC/PC) to the optical ports. Ensure a secure connection.
   • Observe minimum bend radius for fiber cables to prevent signal loss or damage.
6. E1 Connections:
   • Connect your E1 (G.703) devices (e.g., PBX, routers, channel banks) to the E1 ports on the multiplexer using appropriate BNC (75 ohm) or RJ45 (120 ohm) cables, matching the interface type.
   • Ensure proper cabling for transmit and receive pairs if using balanced connections.
7. Ethernet Connections:
   • Connect your Ethernet devices (switches, routers, PCs) to the RJ45 Ethernet ports on the multiplexer using standard Cat5e or Cat6 patch cables.
   • The ports support auto-negotiation for speed (10/100M) and duplex (Full/Half).
8. Orderwire Phone Connection (Optional):
   • If using the orderwire feature, connect a standard analog telephone set to the RJ11 “PHONE” port on the front panel.
9. Initial Power-Up and Status Check:
   • Once all connections are made, power on the connected E1 and Ethernet equipment.
   • Observe the LED indicators on the front panel of the multiplexer. Look for:
     • Power LED (PWR)
     • Optical Link Status (OPT or LNK)
     • E1 Channel Status LEDs (E1_1 to E1_16 – ALM or LOS indicators)
     • Ethernet Link/Activity LEDs (ETH LNK/ACT)
   • A stable optical link and absence of E1 alarm LEDs generally indicate a successful basic setup.
10. Configuration and Testing (If Applicable):
    • Refer to the user manual for any specific configuration settings (e.g., via console port if available, or DIP switches for loopback tests).
    • Perform loop-back tests if necessary to verify E1 channel integrity.
    • Test Ethernet connectivity and data throughput.
    • Test the orderwire phone if connected.
    • If SNMP management is included, configure it according to your network management system requirements.

Disclaimer: These are general installation guidelines. Always refer to the product’s specific user manual for detailed instructions and safety precautions.
