FibroLAN MetroStar 100Base-TX to 100Base-FX with tunneled E1 Modules

The MCM100-E1 module series are 100Base-T to 100Base-FX Media Converters with tunneled E1 port(s) This module provides one Layer 1 100Base-TX to 100Base-FX conversion channel plus one or two E1 channels tunneled over the 100BaseFX link. The module integrates traffic coming from a legacy WAN with 100Mbps from the IP network onto a single bit stream, connected via 100BaseFX to a remote LTA41-E1 where it interfaces customer’s LAN and PABX – and vice versa. When both E1 links are operational, they consume not more than 5% of the Fast-Ethernet bandwidth. Consequently, it allows the migration of existing infrastructure from WAN to Metro Ethernet. It is transparent to duplex mode but performs FDX Advertising (switch selectable) to force duplex mode on its link partner.

The module is offered in a large variety of optical interfaces, both dual and single fiber strand, allowing the extension of the network up to 150km. Fault Propagation from the F/O port to the TP port allows network redundancy (provided that the switch/router to which it is connected is properly set to activate an alternate path). The TEST switch disables FP function and it is used for diagnostics purposes. Its RJ-45 port is Auto-Cross compliant, making installation trouble free. The Subscriber Link Emulation (SLE)- when link partner is an MA enabled device – allows real time notification of the remote user failure while maintaining the fiber link active. The rate limiting mechanism provides the carrier with a platform to ensure SLAs along with high over-subscription rates. Like other MetroStar modules, the MCM100-E1 is fully SNMP managed. The embedded MA chip allows full management of a remote LTA41-E1 device eliminating the need of costly SNMP processors and IP addresses in such devices. All MetroStar modules are hot swappable and equipped with two self-clinching screws for easy and safe module insertion and removal. A special LED indicates that the module is well inserted in its slot and “alive” even before links are connected.
