Notes on Operation:

Language:

There are two Algerian networks with identifiers clearly connected to
the extensive oil and gas fields in the Algerian interior.  It's
therefore very likely that at least one, and perhaps both networks are
operated by SONATRACH -- the Algerian government's energy company.

Although the precise function of each network is unknown they are
probably connected to communications and security operations, and remote
monitoring of the pipes.  SONATRACH is also known to have procured the
Racal MSM-1250 equipment which the ALE on these networks triggers. 

Many ALE identifiers are the names of the fields themselves, or towns
close by.  Identifiers are also seen with the common suffixes "GPL" and
"30P".  The assumption is that GPL is a contraction of Gas PipeLine, but
the origin of 30P is unknown.  Other identifiers carry the actual names
of the pipelines -- for example, Rhourde Nouss which is on the LR1
natural gas pipeline is "RNOUSLR1".  It's likely that the many "SP"
prefixed identifiers are guard posts or pumping equipment stations along
the pipelines.
