Refurbished Telephone System Cards (PBX Cards)
A telephone system card, also called a PBX card or telephony card, is a circuit board that slots into a telephone system to add a function. Cards connect outside lines, digital or analogue extensions, VoIP channels, DECT base stations or voicemail. Each card is made for one system family, so it only fits the system it was designed for.
This range covers refurbished cards from Avaya, Panasonic, Nortel, Samsung, Alcatel, NEC, LG, Siemens, Mitel, Toshiba, Aastra and BT Business. You use them to add extensions, replace a failed card or keep a spare. Cards fit inside a system chassis. For extra ports in a separate unit, see expansion modules.

How to choose a telephone system card
Match the part number
Read the part number on your existing card or in the system manual, such as KX-TDA0170 on a Panasonic DHLC8. The same card name can come in versions for different systems, such as the Panasonic DLC8 and NCP DLC8, so the part number is the safest match.
Choose the extension type
Extension cards are digital or analogue. Digital cards, such as the Panasonic DLC8 or Avaya DS8, run the maker's digital phones. Analogue cards, such as the Panasonic SLC8, run single-line phones, fax machines and door entry units.
Check your line type
Line cards must match your outside lines: analogue, ISDN2 (BRI) or ISDN30 (PRI, E1). UK ISDN is being withdrawn, so check whether your system supports SIP trunks or needs a VoIP card such as the Avaya VCM32.
Check slots and software
Count the free slots in your chassis and check any limits on how many of each card it takes. Some cards need a minimum software release or a licence, so confirm your system's release before you order.
Repair or replace a failed card
If a card has failed, our repair service may be able to fix it. A refurbished card with the same part number is the simplest swap, since your programming stays in the main system.

Questions
What is a PBX card?
A PBX card is a circuit board that slots into a telephone system to add lines, extensions or features. Common types are digital and analogue extension cards, ISDN line cards, VoIP cards and voicemail cards. Each card is made for one system family and only fits that system.
What is the Panasonic DLC4 card?
The Panasonic DLC4 is a 4-port digital extension card. It connects Panasonic digital system phones to the telephone system. Panasonic made versions for different system ranges, so match the full KX part number on your card before you order.
What does the Panasonic DHLC8 card do?
The DHLC8 (KX-TDA0170) is an 8-port digital hybrid extension card for Panasonic KX-TDA systems. Each port can run a Panasonic digital phone or an analogue device such as a single-line phone. It suits sites with a mix of handset types.
Can I find a card by its part number?
Yes. Most cards carry a part number on the label or circuit board, such as KX-TDA0173 on a Panasonic SLC8 or the 9-digit code Avaya uses, like 700315575 on an MM711. Search the site for that number, or send it to us through the quote form.
