NEC SL2100 3-Port Trunk Daughter Board
The NEC SL2100 3-Port Trunk Daughter Board provides an interface for three standard loop-start CO trunks through a single 8-conductor jack. It mounts on 082U, 008U, or 000U cards, with up to four boards per chassis and twelve per system, though it has no power failure transfer circuitry.Overview
The NEC SL2100 3-Port Trunk Daughter Board is a compact expansion accessory that adds central office trunk capacity to the SL2100 PABX platform. It mounts directly onto a compatible 082U, 008U, or 000U card, giving system integrators a straightforward way to add loop-start trunk lines without a full card swap. Multiple boards can be combined across a chassis to scale trunk capacity as a business grows.

Frequently Asked Questions
What is a trunk daughter board and what role does it play in a PABX system?
A trunk daughter board provides connections for external telephone lines (CO trunks) from the telephone company. It expands the number of incoming and outgoing lines your PABX system can handle.
How many phone lines does the SL2100 trunk daughter board add?
The NEC SL2100 3-Port Trunk Daughter Board provides three standard loop-start CO trunk connections, each capable of carrying one incoming or outgoing call simultaneously.
What is a loop-start CO trunk?
Loop-start is a standard telephone company connection type where the phone line operates on a two-wire circuit. It is the most common trunk type for small and medium businesses in many regions.
How many trunk boards can be installed in a single SL2100 system?
Up to four trunk daughter boards can be mounted on each card slot, with up to twelve boards per system, providing substantial trunk capacity for high-call-volume businesses.
What is the downside of using this trunk board instead of more advanced options?
This board has no power failure transfer circuitry, meaning if the PABX loses power, callers cannot be automatically routed to a fallback telephone—a limitation for businesses requiring emergency call continuity.
Which businesses need three trunk lines?
Small offices, satellite branches, or departments with moderate incoming call volume benefit from three dedicated lines. Contact Procure.ae to assess whether three trunks suit your call patterns.
How are the three trunks connected to the board?
The three trunk lines connect through a single 8-conductor jack on the daughter board, simplifying cabling and installation compared to separate connectors.
What are typical delivery times for the SL2100 trunk daughter board in the UAE and GCC?
Procure.ae supplies the trunk daughter board across the UAE and GCC on a request-a-quote basis. Contact the team for stock status, pricing, and estimated delivery.
Is professional installation required to mount this trunk board?
Installation requires opening the SL2100 chassis and proper technical knowledge of PABX systems. Procure.ae can guide installation requirements and recommend professional setup support.
Can this trunk board be mixed with other trunk board types in the same SL2100 system?
Yes, you can install different trunk board types to support various line types (loop-start, ISDN-PRI, etc.). Contact Procure.ae to discuss hybrid trunk configurations for your needs.
What warranty and support come with the SL2100 trunk daughter board?
The NEC SL2100 trunk board is a genuine component with manufacturer warranty. Contact Procure.ae for warranty terms, support options, and availability of replacement service in your region.
