Identifying the different units
Pipeline 50 and 75
The new Pipeline 50 and 75 units have a different pack panel from original
versions. Newer units can use software version 5.0B and higher; older units have
less on-board memory, so be aware that there are different software loads for
each of the units.

Note:
If you have a combination of original and newer Pipeline units, use these
illustrations to determine which units are new. You can tell the difference
between original and newer units by looking for a switch (which is non-
functional) on the back panel.
Figure 2-2. Old (top) and new (bottom) Pipeline 50 back panels
The Pipeline 50 and 75 units now have the same back panel. The POTS ports may
be enabled on a Pipeline 50 by converting the unit to a Pipeline 75. This is done
by obtaining a hash code from the Technical Assistance Center and performing a
software upgrade.
