# osmo-bts-trx(8)

Base Transceiver Station for GSM

## NAME

**osmo-bts-trx** - Base Transceiver Station for GSM

## SYNOPSIS

```
osmo-bts-trx [options]
```

## DESCRIPTION

**OsmoBTS is a software implementation of Layer2/3 of a BTS. It implements the** **following protocols/interfaces:**

- •

  **LAPDm (GSM 04.06)**

- •

  **RTP**

- •

  **A-bis/IP in IPA multiplex**

- •

  **OML (GSM TS 12.21)**

- •

  **RSL (GSM TS 08.58)**

**OsmoBTS is modular and has support for multiple back-ends. A back-end talks to** **a specific L1/PHY implementation of the respective BTS hardware. Based on this** **architecture, it should be relatively easy to add a new back-end to support** **so-far unsupported GSM PHY/L1 and associated hardware.**
