System Upgrades

Upgrade cards for Panasonic phone systems are listed here, such as the KX-TD161R 4-port door phone card, the KX-TD160R 2-port door phone card, a refurbished KX-TD112 clock card and a T-1 card.

Panasonic no longer makes business phone systems, but KX-TD still supplies, programs and supports them. Owners buy these to add door entry, keep correct time on call records or connect digital lines. Call (866) 205-4112 to confirm a card fits your cabinet.

Panasonic system upgrade guide

Door phone cards

The KX-TD160R is a 2 port door phone card, and the KX-TD161R is a 4 port card. Choose by the number of doors or intercom points. Count the doors or call stations you need to cover, and leave one or two spare ports if you plan to add more later.

Clock card and T-1 card

The KX-TD112 clock card, listed as refurbished, keeps a correct time on call records and lets features that depend on time work. The T-1 card connects a digital T-1 line. Check that your cabinet has an open slot for the card.

Telephone and voice processing upgrades

Listings also include a telephone system upgrade, a voice processing system upgrade and a card upgrade. These are general entries, so call us at (866) 205-4112 to say what you want to add and we will confirm what is needed. We can also look at your system and advise on the right upgrade path.
