iConverter GM4
Service Testing and Validation
The GM4 supports ITU-T Y.1564 and RFC 2544 service testing
to easily verify the conguration and performance of Ethernet
services prior to customer hand off. RFC 2544 provides per
ow testing of Key Performance Indicators (KPI), such as
throughput, latency, jitter and frame loss up to full wire speed.
Y.1564 is a comprehensive Carrier Ethernet testing standard
that tests all data ows and service attributes, including multi-
ow Information Rate and Trafc Policing. Y.1564 tests all
performance attributes simultaneously so testing is run quickly
and efciently, and can detect potential interaction between
data ows.
Protection Switching
The GM4 supports ITU-T G.8031 Ethernet Linear Protection
Switching and G.8032v2 Ethernet Ring Protection Switching
with Connectivity Check Messages (CCM) at 3.3ms rate for
sub-50ms protection switching. G.8032v2 includes multi-ring
protection and sub-ring support with 5-Port GM4.
APPLICATION EXAMPLES
In this application example, 5-port GM4 NIDs are deployed
as nodes on a Metro Ethernet ring. 5-port GM4 NID on the
left is deployed as a hub aggregation device that provides
connectivity to the ring and three ber access links to customer
locations. A 2-port GM4 terminates each ber link and provides
service demarcation at each customer premises.
The 5-port GM4 NID on the right is deployed at a Multiple tenant
building with three RJ-45 UNIs providing copper connectivity
to three different subscribers.
In this application example, GM4 NIDs are deployed as
nodes on a wireless backhaul ring. The two 5-port GM4
NIDs connected to the Wireless Backhaul Network provide
NNI functions for the ring. All GM4 NIDs on the ring support
G.8032v2 Ethernet Ring Protection Switching for service
protection with sub-50ms failover.
The 5-port GM4 NID on the right provides G.8032 ring
connectivity and G.8031 linear protection with a redundant
ber access link to the tower. The 3-port GM4 NIDs provide
LTE service demarcation at the cell towers, and all the GM4
NIDs on the network support Y.1588v2 clocking.
Form Factors
The GM4 is available as a compact standalone unit or as a
chassis plug-in module. The hot-swappable plug-in module is
available in 2 and 3-port models, and can be mounted in a 19
or 5-Module chassis with any combination of redundant AC and
DC power supplies. It can also be installed in a 2-Module AC
or DC powered chassis. The plug-in module can function as a
management module and manage other modules in the same
chassis, and operate as a Network Interface Device (NID). It
features two Gigabit Ethernet backplane ports for connectivity
to adjacent modules in a chassis for multi-port and multi-service
congurations. The GM4 plug-in modules also function as a
ber transport module for the modular iConverter Ethernet and
T1/E1 Multiplexer System.
The standalone GM4 is available in 2, 3, and 5 port models.
They are DC powered with a terminal connector and available
with an external AC/DC power adapter. The 5 port model is
available with dual power inputs. The 5-port model supports
any combination of 10/100/1000 RJ-45 copper ports and
100Mbps or 1000Mbps SFP ber ports to provide service
demarcation ports for multiple applications and customers.
