IMS - LANTIME M3000S: Modular Time and Frequency Synchronization
Versatile and Modular Solution for Time and Frequency Synchronization Applications in a Compact
3RU Chassis
The new LANTIME M3000S is a field-upgradeable and extremely flexible system that covers your
synchronization needs - today and in the future. Upgrading to more outputs, new connector and signal types
and protocols is easier than ever with Meinbergs Intelligent Modular Synchronization platform (IMS).
The short version of the LANTIME M3000 chassis is the compact and cost effective alternative to the
standard model. It can be installed in 19 inch racks as well as 21 inch racks (with an adapter). The reduced
mounting depth of the S chassis enables you to mount the system in 300mm ETSI racks. All connections
and control elements are placed on one side, allowing to mount this chassis on a wall or inside a rack that is
only accessible from one side. As the standard M3000 chassis it comes with four power supply slots, two
clock module slots, a seamless switchover card slot, a CPU slot and ten slots for additional input and output
modules. Adding a second clock module and the required RSC switch module will turn the M3000S into a
fully redundant solution. The up to four power supplies that can be installed offer a high level of protection
against the failure of one or more power sources and power supply failures. Both wide range AC and DC
power supply models can be mixed and matched as required.
The possibility to add input and output modules as well as specialized communication cards for NTP and
PTP/IEEE1588 network synchronization (including Synchronous Ethernet support) and remote management
ensures that a LANTIME M3000S will fulfill all your synchronization requirements and the scalability and
flexibility of the IMS platform concept enables it to cope with the changing demands of your critical
All modules support hot plugging, allowing to replace faulty modules or add new capabilities to the system
with zero downtime for unaffected modules and functions.

options for your NTP server
- Up to 40 additional LAN ports
Just like the M3000 standard model, the LANTIME M3000S supports the following slot types:
* IMS-CLK: Up to two reference clock modules (redundant mode)
* IMS-SCU: Accepts an RSC module for redundant operation (two CLK modules installed) or an SPT module for a
single CLK configuration
* IMS-PSU:Up to four high efficiency redundant power supplies (AC and DC versions available)
* IMS-CPU: Central processor module providing NTP / SNTP time synchronization as well as remote and local
management and configuration interfaces
* IMS-IO: A variety of output signals for all types of synchronization tasks:
electrical and optical pulses, frequencies, time codes and serial time messages as well as additional network interfaces
for network synchronization (IEEE-1588, NTP, Synchronous Ethernet) and additional remote management capabilities
Includes: High-End NTP Network Time Server for your Network
With several thousand NTP requests per second (depening on the installed CPU module), the system is able to provide
time for hundreds and thousands of NTP clients. The LANTIME management CPU module supports the following
protocols: NTP / SNTP (v2, v3, v4), HTTP (S), SSH, Telnet, SNMP (v1, v2, v3), FTP, SFTP, DHCP/DHCPv6. For each
system, up to 99 logical network interfaces are available (99 IPv4 and 99 IPv6 addresses, each logical interface can be
assigned to one VLAN ID). Enterprise-grade features such as IPv6/Dual Stack support, IEEE 802.1Q VLAN support,
LACP/high availability bonding as well as DSCP and IEEE802.1p QoS/CoS traffic prioritization ensure that this product
can be installed and operated in almost every critical environment: a financial data center; an electrical substation; an
NGN telecommunication network; a digital broadcasting infrastructure ; air traffic control systems and many many other
Scalable Synchronization Solution
All modules are hot-pluggable and can be configured via a central web interface or a CLI. An almost endless number of
combinations of input and output modules handles almost any synchronization task and allows the system to fit into
many different roles. The field-upgradeable and therefore highly scalable and flexible IMS concept will grow with your
demands. New technologies can be easily integrated into your existing devices as soon as a corresponding module is
available, supporting a new connector, signal type or protocol. This protects your investments as it removes the
requirement to replace existing devices or add complete new systems when your sync requirements change.Flexible

IMS-MRI:Standard reference input cards supporting a number of different input signals like 1PPS, 10MHz, IRIG DCLS,
IMS-ESI: Extended reference inputs for synchronization sources like E1/T1 framed and unframed signals
Both of these slot types can alternatively accept I/O cards and therefore can be used to add output modules or network
interfaces, resulting in a maximum of 10 output modules per chassis in combination with the 6 I/O slots.
Due to the hot-plug capabilities of the IMS platform it is possible to add additional modules or replace modules with zero
downtime and no negative impact on the system and its modules.
Power supply failures and a large number of additional synchronization related alarms can be communicated using
several different protocols, for example mail/SMTP messages, SNMP traps, SYSLOG messages, or alarm relay cards.
IMS Modules
Most standard output signals like pulses (1PPS, 1PPM, programmable pulses) and frequencies (10MHz, 2.048MHz,
frequency synthesizer 1kHz-10MHz) are provided by two versatile I/O cards named BPE and CPE. Both of these two
modules have been designed to cover a wide range of interface and signal/protocol requirements. They feature a
two-tier architecture with a back-end and front-end. While the back-end is responsible for internally routing the
backplane IMS synchronization signals (in case of the BPE) or for autonomously generating a wide range of different
signals by using a microprocessor (on a CPE), the front-end makes a selection of the signals available on physical
connectors. Due to this design, it is very easy to support a large number of different electrical or optical physical
interfaces, like BNC, SMA, Twinax, 2-pin DFK, DSUB9 and ST/SC FO connectors.
An impressive number of specialized IMS modules covers other application requirements, for example E1/T1
framed/unframed synchronization signals with full SSM/BOC support or low phase noise 10MHZ sine wave frequency
outputs. Additional network interfaces for NTP, PTP/IEEE 1588, SyncE and remote management access are available,
