Alcatel-Lucent 11075L-128 810-00206-28 CBX 500 Card

Description

Product Introduction & Engineering Value

The Alcatel-Lucent 11075L-128 is a legacy CBX 500 ATM processor card designed for four OC-3/STM-1 interfaces. Its 128 MB memory configuration distinguishes it from the 32 MB version associated with the 11075L base model. The card provides ATM flow-control processing and is identified as APS-capable in multiple equipment catalogs.

For procurement, use the complete identifier 11075L-128 / 810-00206-28. Secondary-market records also associate this hardware with BAC328WEAA, while other revisions and assembly identifiers exist under the same 11075L-128 family.

Technical Specifications

A separate reseller catalog lists 11075L-128-REV-2 / 810-00206-28 / BAC3282EAA with the same four-port OC-3/STM-1, 128 MB, APS-capable description. This indicates that revision and assembly identifiers need to be checked carefully when matching a field spare.

Interface Context

OC-3 corresponds to approximately 155 Mb/s, while STM-1 is the corresponding SDH designation. The 11075L-128 therefore belongs to the older SONET/SDH ATM transport generation rather than modern Ethernet-based switching hardware.

Field Application & the “Trench” Experience

Consider an older carrier POP still operating a CBX 500 ATM network. Three OC-3/STM-1 links remain active, carrying legacy ATM services that have not yet been migrated. One processor card begins reporting persistent interface errors. The network team has no interest in replacing a functioning CBX 500 shelf just to eliminate one failed card.

The correct maintenance approach is a like-for-like identification: 11075L-128, 810-00206-28, 128 MB. The engineer then checks the revision and assembly identifier before installing the spare.

Specific application scenarios

1. Legacy ATM aggregation — terminate multiple OC-3/STM-1 links on a CBX 500 platform.
2. SONET/SDH ATM access — process ATM traffic transported over OC-3/ facilities.
3. APS-protected carrier nodes — support an existing architecture where automatic protection switching is part of the deployed configuration.
4. Migration-stage telecom POPs — maintain legacy ATM infrastructure while services are progressively migrated to packet-based networks.

The 11075L-128 is repeatedly cataloged specifically as a four-port OC3/STM1 ATM flow-control processor with 128 MB RAM.

Transparency SOP — QA & Testing

For a New Surplus or refurbished unit, the inspection should be specific to this legacy ATM card.

1. Label verification — confirm 11075L-128 and 810-00206-28.
2. Assembly verification — record BAC328WEAA, BAC3282EAA, or the exact assembly marking present.
3. Revision check — document the revision before approving it as a replacement.
4. PCB inspection — examine connectors, edge contacts, components, and evidence of corrosion or overheating.
5. Memory verification — confirm the 128 MB configuration rather than accepting the visually similar 32 MB 11075L version.
6. Functional test — in a compatible CBX 500 test environment, verify card recognition, OC-3/ ports, ATM processing, alarms, and APS behavior where applicable.

Current marketplace evidence includes a used 810-00206-28/BAC3882EAA unit described as pulled from a working environment. That means procurement should explicitly define New OEM, New Surplus, or Refurbished rather than relying on a generic “working” description.

The Veteran’s Tech Trap Guide

⚠️ Trap #1 — Confusing 11075L with 11075L-128

This is the big one.

The standard 11075L is documented with 32 MB RAM, while the 11075L-128 is the 128 MB version. The part number also changes from 810-00206-01 to 810-00206-28.

PRO TIP: Never write only “11075L” on the RFQ.

Use:

11075L-128 / 810-00206-28 / 128 MB

⚠️ Trap #2 — Ignoring revision and assembly identifiers

Listings associate 810-00206-28 with several assembly/revision identifiers, including BAC328WEAA and BAC3282EAA. Match the failed card’s complete label against the approved spare documentation.

⚠️ Trap #3 — Treating OC-3 and as unrelated interfaces

They are the SONET and SDH designations for the same approximate 155 Mb/s optical hierarchy level. The important issue is the actual CBX 500 card and network configuration, not simply whether the purchase description says “OC-3” or “.”

⚠️ Trap #4 — Assuming any CBX 500 optical card is interchangeable

The CBX 500 family contains several processor and I/O cards. For example, the 11058L-128 is a different OC-3/ processor family, while the 11076A-128 is associated with OC-12/STM-4.

Dynamic FAQ

Q1. What is Alcatel-Lucent 11075L-128?
It is a CBX 500 four-port OC-3/ ATM Flow Control Processor Card with 128 MB RAM, identified by part number 810-00206-28.

Q2. What is the difference between 11075L and 11075L-128?
The 11075L is documented as the 32 MB version using 810-00206-01, while the 11075L-128 uses 810-00206-28 and provides 128 MB RAM.

Q3. How many optical ports does the 11075L-128 have?
The documented configuration has four OC-3/ ports.

Q4. Is 810-00206-28 APS-capable?
Yes. Multiple equipment catalogs explicitly describe the 11075L-128 as APS capable.

Q5. Is BAC328WEAA the same part?
It is an assembly identifier associated with the 11075L-128 / 810-00206-28 configuration in reseller catalogs. Because multiple assembly and revision identifiers appear in the market, verify the complete label before declaring two units interchangeable.

Q6. Is New Surplus 11075L-128 available?
Secondary-market availability exists, but condition varies. Current listings include used units, so a New Surplus purchase should require label photographs, serial/traceability information, functional-test confirmation, and written warranty/DOA terms.
