4. Product Introduction & Supply Chain Strategy
The Alcatel-Lucent DFP-CM-14B-2T is a specialized Ethernet circuit pack designed for the 1665 Metropolis DMX platform. It enables service providers to offer transparent LAN services over existing SONET infrastructure by mapping Ethernet frames into virtual containers. This module is the primary hardware interface for delivering high-reliability B2B data services and backhaul traffic within a TDM-dominated environment.
Maintaining a New Surplus DFP-CM-14B-2T on-site is a strategic supply chain imperative for aging Metro networks. Refurbished Ethernet cards frequently exhibit “silent failures,” such as intermittent CRC errors or port-flapping caused by dried-out electrolytic capacitors from decades of use. By investing in New Surplus inventory, you secure the original factory-validated signal integrity. This mitigates the risk of a “truck roll” that costs thousands in labor and fuel, only to find that a second-hand replacement card is also faulty.

5. Installation & Configuration Guide
Stage 1: Pre-Installation (Prep & Safety)
Ensure the 1665 DMX shelf has a compatible slot pair available (this is often a dual-width card). Verify that the SONET cross-connects are provisioned for the required bandwidth (VT1.5 or STS-1). Mandatory: Use an ESD-safe wrist strap; Ethernet PHY chips are highly sensitive to static discharge during the physical seating process.
Stage 2: Removal
If replacing a card, use the Craft Interface Terminal (CIT) to put the existing ports into “Maintenance” mode. Pull the locking tabs on the faceplate to disengage the module from the backplane. Inspect the backplane pins for any misalignment before proceeding.
Stage 3: Installation (Clone & Seat)
Slide the DFP-CM-14B-2T firmly into the guide rails. Ensure the card is fully seated and the locking levers are flush with the faceplate. This establishes the critical grounding path for the RJ45 shielded ports.
Stage 4: Power-On & Testing
Watch the “FAULT” LED. It should flash briefly and then go dark. Use the CIT to verify the hardware revision and “EQUIP” the card in the software database. Perform a ping test from a connected laptop to verify the local 10/100 copper link is active before connecting the long-haul traffic.
6. Firmware/Software Versions & Upgrade Notes
The DFP-CM-14B-2T requires Metropolis DMX software Release 4.0 or higher. If your shelf is running an earlier version, the card will remain in an “unassigned” state.
Compatibility Note: When replacing this module, check the “B” revision in the model number. If your system was originally provisioned for a “14A” series card, there may be slight differences in LCAS (Link Capacity Adjustment Scheme) behavior. Ensure the system software supports the “14B” hardware features to avoid protocol negotiation failures.
7. Frequently Asked Questions (FAQ)
What is the difference between New Surplus and Refurbished for this card?
Our New Surplus DFP-CM-14B-2T units have zero hours of operational heat cycles. Refurbished units have likely been running in 24/7 telecommunications environments for 10+ years, which significantly degrades the MTBF (Mean Time Between Failures) of the Ethernet controllers and power regulation circuits.
Does this card support Gigabit Ethernet?
No, the DFP-CM-14B-2T is strictly for 10/100 Base-T copper connections. For Gigabit requirements, a different Metropolis DMX series card (such as the LNW64) is required.
Can I use this card for VLAN trunking?
Yes, the module supports 802.1Q VLAN tagging, allowing you to multiplex multiple client networks over a single SONET virtual concatenation group.
Is it normal for the ports to stay dark after plugging in a cable?
The ports will remain inactive until they are administratively “In-Service” (IS) through the management software. If the LEDs are dark after provisioning, check your cable pinouts (T568B standard).
What is the warranty period?
We provide a 12-month replacement warranty on this New Surplus unit. This covers any hardware defects and ensures your legacy infrastructure remains operational without the high costs of OEM support contracts.
