About the E4G Series Routers
This chapter describes the Extreme Networks E4G series routers and includes the following sections:
●Overview on page 13

●E4G-400 Cell Site Aggregation Router on page 20

Overview
The Extreme Networks E4G router family consists of the E4G-200 series cell site routers (E4G-200 and
E4G-200-12x), and the E4G-400 cell site aggregation router. These routers provide high-bandwidth
capacity, highly accurate and flexible timing, and Operations Administration and Maintenance (OAM)
capabilities that support service level agreement (SLA) metrics. They support time-division multiplexing
pseudowire end-to-end emulation (TDM PWE3). PWE allows the simultaneous support of multiple
generations of services (2G, 3G and 4G) over the same Ethernet backhaul network without having to
remove legacy T1/E1 equipment and incur associated costs.
The E4G-200 Series Cell Site Routers collect traffic from cell site towers for handoff to the mobile
backhaul network. The E4G-200 series routers connect to the E4G-400 Cell Site Aggregation Router,
which aggregates T1, E1. and Ethernet traffic for handoff to the mobile core (see Figure 1).

Figure 1: Mobile Backhaul Architecture
E4G-200 Series Cell Site Routers
There are two models in the E4G-200 series: the E4G-200 and the E4G-200-12x.
E4G-200 Cell Site Router Overview
The Extreme Networks E4G-200 router provides 12 resilient synchronous Gigabit Ethernet ports (eight
RJ-45 and four SFP) and 16 T1/E1 ports in a compact 1RU unit. The Ethernet ports support both IEEE
1588v2 and Synchronous Ethernet (SyncE) timing, and the T1/E1 ports support time division
multiplexing (TDM) timing.
The E4G-200 router provides high-performance pseudowire capability, supporting both CESoPSN
(channelized) and SAToP (unframed and unchannelized) TDM services. Deployed at the cell site,
E4G-200 router collects traffic from 2G, 3G, and 4G radio towers for handoff to the mobile backhaul
over fiber or microwave.
The E4G-200 router’s extended temperature range of -40°C to +65°C allows service providers to deploy
the E4G-200 router at sites without climate control.
The E4G-200 cell site router front panel (Figure 2) has the following features:
●Alarms port implemented as a DB-15 connector.
For details about the connector, see “E4G-200 Series Connector Pinouts” on page 126.
●Management and console ports
●Eight 10/100/1000BASE-T (RJ-45) dedicated ports

E4G-200-12x Cell Site Router Overview
The Extreme Networks E4G-200-12x router provides 12 Gigabit SFP ports and 16 T1/E1 ports in a
compact 1RU unit. The Ethernet ports support both IEEE 1588v2 and Synchronous Ethernet (SyncE)
timing, and the T1/E1 ports support time division multiplexing (TDM) timing.

E4G-200 Series Alarms Interface
The alarms interface for both the E4G-200 and E4G-200-12x routers is implemented as a DB-15 female
connector. This interface relays alarms to an external device (output alarms) and monitors alarms from
an external device (input alarms). The alarms are controlled from the ExtremeXOS software.
The alarms interface provides two input alarms and eleven output alarms. Input alarms can be
configured to monitor alarms from an external source and raise a trap or flag, or to be an input source
to clear Minor or Major alarms. The output alarms can be connected to an external visual or an audible
interface. The output alarms can be either persistent or non-persistent. For information about
configuring alarms, refer to the ExtremeXOS Concepts Guide.
For details about the connector, see “E4G-200 Series Connector Pinouts” on page 126.
E4G-200 Series Power Supply
Both the E4G-200 and E4G-200-12x routers have an integrated DC power supply with dual feeds on the
front panel. Power feed A can be connected to one power source and power feed B can be connected to
a different power source to provide protection should either source of power fail. The power supply is
not field-replaceable.
The back panel of the E4G-200 and E4G-200-12x router provides an alternate attachment point for the
grounding lug.

E4G-200 Series CLK Module
An optional clock module (Figure 4) for both E4G-200 Series routers provides timing based on either of
the following protocols:
●ITU-T Synchronous Ethernet (SyncE) protocol
●Precision Time Protocol based on the IEEE specification 1588v2
The clock module has four mini-BNC connectors providing Sync In/Sync Out timing interfaces and an
RJ-45 connector that provides an RS-422 BITS-IN interface. Clock modules can be installed or removed
without powering down the router, although a system reboot is required to initialize the module.
Figure 4: E4G-200 Series Clock Module
E4G-200 Series F16T1E1 Module
The F16T1E1 module for both E4G-200 Series router provides 16 T1/E1 ports implemented as RJ-45
connectors (Figure 5. These support circuit emulations via industry-standard pseudowires, allowing the
transformation of TDM cell sites to Ethernet/IP/MPLS cell sites. T1/E1 modules can be installed
or removed without powering down the router, although a system reboot is required to initialize
the module.

E4G-400 Cell Site Aggregation Router
The E4G-400 cell site aggregation router is a 1RU unit that allows networks to aggregate multiple
Ethernet links from various cell sites and route the traffic to the mobile core. The E4G-400 router
provides 28 Gigabit Ethernet ports and port options for up to six 10-Gigabit Ethernet ports, as well as a
16-port T1/E1 module with pseudowire capability. The T1/E1 module is used where 2G and 3G radios
are co-located at the aggregation site, and eliminates the need for separate cell site routers.
The Gigabit and 10-Gigabit Ethernet ports on the E4G-400 router support Synchronous Ethernet (SyncE)
and IEEE 1588v2 timing. Integrated timing connectors on the front panel provide timing based on either
the ITU-T Synchronous Ethernet (SyncE) protocol or the Precision Time Protocol based on IEEE
specification 1588v2. Four mini-BNC connectors providing Sync In/Sync Out timing interfaces and an
RJ-422 connector provides a BITS-IN interface.
The E4G-400 router has 4 shared ports. For each pair of shared ports, either the 10/100/1000BASE-T
port (RJ45) or 100/1000BASE-X (SFP) port can be used as needed.
The E4G-400 router supports stacking using ports on installed port option cards at the back of the unit.
Up to eight units can be connected into a single management entity that has up to 192 Gigabit Ethernet
ports and up to 32 10-Gigabit Ethernet ports.
At the back of the unit are two bays for either AC or DC power supplies. One 300 W AC or DC power
supply is included with the base unit. A redundant power supply must be ordered separately. You can
mix any combination of 300 W AC and DC power supplies based on the need at the particular site. For
example, you can have a DC main power feed and an AC input backup from an uninterruptible power
supply (UPS).
