Panasonic Business Telephones

Reboxed and open box Panasonic cards are listed here. Choose from a 16 port echo cancellation card, a doorphone interface card, a fax interface card or a 4 port analog trunk card.

Panasonic stopped making business phone systems, but KX-TD still supplies and supports them. Owners buy these cards to connect a door phone, add outside lines or reduce echo on IP calls, usually at a lower cost than new. We can also help when you are ready to move to VoIP. Call (866) 205-4112.

Before you order

  • Match the card to your cabinet. Each card is made for certain Panasonic systems, so check your cabinet model before you order.
  • Check the card type. Listings include echo cancellation, doorphone, fax interface, VoIP DSP, PRI23, LCOT6 and EXP-M cards.
  • Reboxed and open box. Items marked REBOXED or OPEN BOX are not new factory sealed stock, so read the product name.
  • Not sure? Send your system model and we will confirm the right card.

Panasonic system card buying guide

Cards that add lines

The 4 port analog trunk card and the 6 port LCOT6 card connect outside analog lines to your system. The PRI23 card connects a PRI circuit. Count your lines before you pick, and keep in mind that each card plugs into a certain slot in the cabinet.

Cards that add features

The doorphone interface card connects a door phone. The fax interface card lets a fax machine work with the system. The 16 port echo cancellation card and the VoIP DSP card, S type, handle voice over IP calls. Match each to what your system supports.

Expansion cards

The 3 port expansion master card, EXP-M, is an expansion card for the system. Check the full list of cards in your cabinet and ask us if you are not sure it applies. Ask us if you are unsure how many shelves your system has.

Reboxed and open box items

Some cards are listed as reboxed or open box. These have been returned or opened, and they are usually offered at a lower cost than new. Read each product name, since the condition is part of the listing. Ask us about the exact condition if it matters for your site.
