initial checkin of manuals to public repo The manuals existed in different form for several years in an internal sysmocom repository. However, since they had just recently been converted from docboox-xml to asciidoc and all files have been re-shuffled for enabling the public release, there's not much point in keeping the history with git-filter-branch.

OsmoBTS Abis Protocol Specification
===================================
Neels Hofmeyr <nhofmeyr@sysmocom.de>
== Introduction
This document describes the A-bis interface of *OsmoBTS*. Based on 3GPP TS
12.21 and 08.58, this document indicates which of the 3GPP specified A-bis
messages and IEs are implemented according to 3GPP specifications, which of
these are not or not fully implemented, as well as OsmoBTS-specific extensions
to the A-bis interface not specified by 3GPP.
Extensions to the A-bis interface specific to OsmoBTS are detailed in this
fix various typos across all manuals

== Overview
The OsmoBTS A-bis interface consists of traffic management messages (RSL, Radio
Signalling Link) and network management messages (OML, Operation & Maintenance
Link), encapsulated in an IPA multiplex.
OML and RSL each use a separate TCP connection.

|===
|TCP Port Number|Usage
|3002|A-bis OML (inside IPA multiplex)
|3003|A-bis RSL (inside IPA multiplex)
|===
Both TCP connections for OML and RSL are established in the BTS -> BSC
direction, i.e. the BTS is running as a TCP client, while the BSC is
running as a TCP server.
The BTS first establishes the TCP connection for OML. Via OML, the BSC
instructs the BTS to which IP address the RSL connection shall be
established.

=== Identities
The BTS is locally configured (via administrative means, out of band of
this specification) to have a Unit ID. The Unit ID consists of three
parts:
* The Site Number
* The BTS number at the site
* The TRX number within the BTS
