Overview

Depending on the installed modules and the selected synchronization sources, the 4U rackmount LANTIME M4000 can play different roles. By supporting multiple input sources utilizing Meinberg‘s IRSA (Intelligent Reference Switching Algorithm) technology, the M4000 accepts GPS, GLONASS, PTP, NTP, SyncE, 1PPS or E1/T1 as possible synchronization inputs to be able to act as an Edge Grandmaster Clock. IRSA is useful to bridge potential GNSS outages or, if desired, completely avoid depending on GPS/GLONASS availability. A highly stable oscillator ensures a holdover period of several hours or days depending on the target application even if no synchronzation source is available anymore. Using an external PRC allows to extend the holdover capabilities to whatever level is required at a certain point in the network.
The PTP implementation support both ITU-T profiles, ITU-T G.8265.1 for frequency and ITU-T G.8275.1 for frequency and phase. This allows to provide accurate frequency and phase synchronization over packet networks to all network elements requiring synchronization, including 2G/3G/4G base stations as well as LTE advanced networks. The M4000 can act as a Telecom Grandmaster for hundreds of clients.

For NTP-based synchronization, each of the TSU module network interfaces of the LANTIME M4000 can be configured to act as a carrier grade NTP server with 10 ns time stamp accuracy, serving up to 12000 NTP requests per second on each port.

The M4000 supports up to 40 pulse and frequency outputs like PPS, 10 MHz as well as software selectable T1 or E1 outputs to synchronize Telecom equipment or measurement devices.

The modular approach of the IMS platform allows field-replacement and hot-swap capabilities for IO modules and power supplies. This concept ensures future-proofness and expandibility by allowing to add or replace modules when new technologies or interfaces are required and makes this product one of the most scalable and flexible synchronization solutions on the market.
