SES ALXLC Alliance Line Card for 12 Phone Connections
The SES ALXLC is the Alliance line card used for groups of 12 telephone connections in the Select Engineered Systems Alliance / Alliance Voice Processor platform. In an Alliance system, line cards are the service components that let the telephone access processor interface with multiple resident or tenant phone lines.
This card is commonly used in apartment buildings, condominiums, offices, and other multi-tenant properties that rely on building telephone wiring rather than a standard monthly central-office telephone line for each entry call path. The Alliance platform can be expanded with multiple ALXLC cards and additional line expansion panels when the system design requires more phone-line capacity.
Correct fitment matters because this is a platform-specific card. A similar-looking SES board from a TEC, CAT, SG, or card-access system should not be treated as a direct replacement.

Technician Note
If multiple tenants or phone stations fail together, the ALXLC may be involved, but cabling, interface blocks, programming, and expansion-panel issues can create similar symptoms. Confirm the failure pattern before replacing the card.
Before Ordering
- Confirm the system is an SES Alliance / Alliance Voice Processor.
- Match the existing board label to ALXLC.
- Count existing line cards and note which position is being serviced.
- Inspect the ALRJ71C block and interface cable before replacing the card.
- Confirm whether any additional programming or system restart is required after service.
Professional Advisory
Line-card replacement in a multi-tenant telephone access system can affect multiple residents or phone stations. Schedule service carefully and use a qualified SES/access-control technician when possible.
Product Questions & Answers
How many phone connections does the ALXLC support?
The ALXLC is listed as a 12-phone line card for the SES Alliance system.
Does this card work with the ALXLEP panel?
Yes, it is commonly used with ALXLEP line expansion panels in Alliance Voice Processor installations.
Is this compatible with TEC1 or TEC2 telephone entry units?
Do not assume compatibility. ALXLC is an Alliance line-card component, not a general TEC replacement board.
What related parts should be checked with this card?
Check the ALRJ71C telco interface block, ALXBL6 or ALXCBL6 interface cable, and the ALXLEP expansion panel.
Can this card fix one resident phone not ringing?
Possibly, but a single resident issue may also be wiring, programming, telco block, or phone-line related. Diagnose before replacing the card.
