3 | 2 | laforge | This wiki describes work within the Osmocom community to develop E1/T1 hardware interfaces. |
4 | |||
5 | E1/T1 lines were pretty common in the 1990ies and up until about 2010, as they built the heart of many connections to the digital, circuit-switched telephony (ISDN) network. |
||
6 | |||
7 | Today (2019), E1/T1 are mostly only found in connection with GSM base stations (BTS), where the Abis interface of a BTS is still officially only specified over E1/T1. |
||
8 | |||
9 | Hardware for connecting E1/T1 to a (Linux) computer has always been expensive, and is rather difficult to find. Also, it only comes in PCI and PCIe form-factor, making it unsuitable to many popular embedded Linux platforms (whether ARM or x86) which don't feature such interfaces. |

11 | We've been wokring on creating E1-USB adapters based on a variety of approaches, see further wiki pages for details. |
