About the GAM

GAM Installation and Activation Guide
Positron Access Solutions 8 Document 180-0186-001 R03
1.1 Introduction
The GAM is a Fiber to the Distribution Point (FTTDp) solution typically installed
inside a wiring closet. Each GAM comes with two (2) 10 Gigabit SFP+ interfaces
to support any type of fiber or PON standards (using an SFP-based or external
ONT as required that is compatible with the OLT). These SFP+ ports can further
support additional GAM devices in medium to large MDUs and share the fiber
backhaul link.
The ITU-T G.9960 G.hn Wave-2 standard leverages the existing telephone wiring
(UTP, CAT-3 or CAT-5/5e) or RG-6/RG-59 coax cabling to deliver a Gigabit
Internet service to each subscriber without the cost, complexity and delays
associated with in-building fiber installation. G.hn is an Access technology for
Operators looking to simplify their access network and backend infrastructure
with an Ethernet-like technology that is highly scalable without some of the
inherent complexity of DSL-related technologies. With G.hn, Operators deliver
advanced services such as Gigabit High Speed Residential Internet and 4K IPTV
without the high capital and operational expenses associated with a fiber retrofit.
Each G.hn subscriber port supports up to 1.7 Gbps of dynamically allocated
bandwidth for near symmetrical Gigabit services over the existing telephone wire
or coaxial cable. The Positron GAM solution is MEF CE 2.0 compliant and is
ideally suited to deliver Business Ethernet services in an MDU and/or MTU
deployment.
Note: Read Chapter 5 Safety and Warnings before proceeding.

1.2 GAM Connections
All ports and connectors of GAM devices are located on the front of the device.
Figure 1: GAM-12-M Front Plate
Figure 2: GAM-24-M Front Plate
Figure 3: GAM-12-C Front Plate
Figure 4: GAM-24-C Front Plate
1.2.1 Power Connection
The GAM devices require local 110-220Vac power and come with a country-
specific power cord. The power connector incorporates an ON/OFF power
switch. A field-replaceable fuse (250v / 5A 5mm x 20mm cartridge type time lag
(slow blow) is part of the AC power connector housing as per the following
illustration.
Figure 5: GAM Power Input Connector
Field-replaceable fuse, remove from
cover to access the fuse.

1.2.2 Ethernet (SFP+) Ports
Figure 6: GAM SFP+ Connectors
The GAM has two (2) SFP+ ports that support any MSA-compliant SFP/SFP+
modules. (Fiber: 1G, 10G and Copper RJ-45: 100M, 1G)
Second uplink allows you to:
Increase overall capacity
oEither via Link aggregation, or
oBy splitting subscriber traffic between the two uplinks.
Uplink protection
oLACP
oRing G.8032
oPoint to point G.8031
Daisy chain another GAM
Important note: When connecting the SFP+ port to a Passive Optical Network
(PON) fiber connection, please make sure to use an Optical Network Unit (ONU)
approved by the OLT vendor you are using.
1.2.3 G.hn Ports
The GAM-12-M has 12 G.hn RJ-45 ports and the GAM-24-M has 24 G.hn RJ-45
ports. When connecting a single telephone pair to an RJ-45 port (SISO mode),
you need to use the “inner” pair. When connecting a second pair (MIMO mode),
the second pair needs to be connected to the “outer” pair.
Figure 7: GAM G.hn RJ-45 Connectors
NOTE: RJ-45 or RJ-14 cables can both be used to connect to the GAM
