IMS-CPE: Backend/Frontend for Configurable Output Modules

This product is only compatible with Meinberg's line of modular IMS LANTIME systems.
Visit the IMS Information Page to learn more.

The IMS CPE modules consist of a half-size standard controller card (back-end) and a dockable port expander card (front-end), enabling a wide variety of available programmable output signals and physical connections, including the different electrical and optical interfaces.

The IMS CPE modules follow a two-component concept in which the back-end uses the reference signals from the backplane and generates the output signals with its own microprocessor. The front end then makes the signals available at a wide variety of sockets. This allows a broad range of supported connection types such as BNC, RJ-45, 2-pin. DFK, DSUB9 and optical interfaces (ST).

Product Description

Compared to an IMS-BPE card, the output signals are generated directly on the CPE module (backend). The 10 MHz and PPS references provided by the upstream clock are used as reference signals. The generated signals are then output via the front end. This has the advantage that the output signals do not have to be configured on the receiver module, but directly on the CPE module. This significantly increases the number of possible output signals in an IMS system. Parallel operation of BPE and IMS cards is also possible without any problems.

The IMS-CPE can be configured to output a wide variety of signal types:

1PPS, 10 MHz
Time Codes: IRIG A/B/E/G/AFNOR/IEEE1344/C37.118/NASA36
Frequency Synthesizer (TTL)
Programmable Pulses: 1PPS, 1PPM, 1PPH, Timer, Single Shot
Cyclic Pulses, DCF77 Mark, Sync Status
Serial Time Strings (RS-232 or RS-422 / 485)

The following IMS CPE modules are currently available:

CPE Module	Connectors	Signal Outputs
