Shelf

Shelf
The TimeProvider is available in two configurations: Model 1000 Front Access and

Model 1100 Rear Access.

Model 1000 Front Access

The ETSI-style shelf (990-58001-01) complies with ETSI 300-119 shelf projections.
Each shelf accepts one IMC and one or two IOCs; the shelf also supports one Input
module and from one to four Output modules. Each Output module terminates eight
output timing signals. Alarms terminate on wire-wrap or DB-25 connectors,
depending on the Input module used. The minimum configuration is one IMC and
one IOC for non-protected operation. Using two IOC modules provides protection in
case one of the IOC modules fail. See
shelf systems.
Model 1100 Rear Access
The NEBS-style shelf (990-58101-01) accepts one IMC and one or two IOCs; the
shelf also supports one Input module and from one to four Output modules. Each
Output module terminates eight output timing signals. Alarms terminate on
wire-wrap or DB-25 connectors, depending on the Input module used. The
minimum configuration is one IMC and one IOC for non-protected operation. Using
two IOC modules provides protection in case one of the IOC modules fail. See
2-5 for part numbers for rear-access shelf systems.

Expansion Panel

The available Expansion Panel provides additional outputs from the main shelf. Like
the main shelf, it comes in two configurations: Model 1000 Front Access and Model
1100 Rear Access. The Expansion Panel supports up to 32 additional output
channels. Both panel kits contain rack mounting ears and extenders for 19-inch and
23-inch racks.

Front Access

The front-access Expansion Panel (part number 990-58002-01) provides an
additional 32 outputs, for a system total of 64 outputs. The ETSI-style Expansion
Panel supports up to four additional Output Modules with various connector types;
each Output Module provides up to eight output signals. See
numbers for Output modules.
