[SML] Telephone line simulator

[Jerry Durand]

I have an old Viking DLS-200B telephone line simulator box.  This is the
box where you plug two landline phones in.  When you pick up one the
other rings and you can now talk.  Even supplies dial tone and ring-back.

Can be used for ringing phones or as a two station intercom.  This was
used to demo telecom gear at trade shows and also to test prototypes.

Free to a needy theatre, but pay for postage.

Original instruction manual included.
