More info

Digium’s new TE131, TE132, TE133 and TE134 single span digital cards are the latest additions to the Telephony Card family. The TE13x design utilizes state of the art technologies to support T1/E1/PRI environments that require a high-performance, cost effective digital telephony interface card. The TE13x family of cards have the ability to create a seamless network, interconnecting traditional telephony systems with Voice over IP technologies.

The TE13x family of cards support industry standard telephony protocols, including Primary Rate ISDN (both North American and Euro Standard) protocol families for voice. Both line-side and trunk-side interfaces are supported, as well as advanced call features. TE133 and TE134 model cards feature Octasic-based hardware echo cancellation that is built in to the cards, removing the task of echo cancellation from the systems CPU and increasing overall system performance and call quality. TE131 and TE132 model cards are for environments that do not require hardware-based echo cancellation, instead relying only on software echo cancellation.

Digium cards are compatible with all versions of Asterisk using the DAHDI driver framework. Asterisk and DAHDI are available for free from the Asterisk.org website. All cards include a five (5) year warranty and are eligible for Digium's no-risk ESP guarantee.

The Digium TE131F card can be simply connected to a PCI Express slot. The T1 port connects your phones and other phones to the PBX. This card supports 24 simultaneous calls to T1 or 30 calls with E1.
An echo cancellation module is not supported and can not be installed in the Digium TE131F.

  • Number of Doors: 1 x RJ48

The TE131 and TE132, unlike many Digium digital cards, cannot be upgraded in the field with modular hardware-based echo cancellation
The TE131, TE132 are not compatible with Switchvox. Use the TE133 or TE134 with Switchvox for single span digital connectivity.
