1. Introduction
1-1 Functional Description
The PacketLINK family is a “Multi-service (TDM and Ethernet) over Ethernet” bridge, which
transports up to 16 ports of E1 and one LAN over an Ethernet network. Its target application is
the replacement of E1 leased lines, by enabling the interconnection of E1 equipment via an
Ethernet WAN circuit.
The E1 over IP algorithm is compliant with the IETF “CES over IP” standard. LEDs are
provided for alarms and status indication.

Reset Button
Use this button to restart the system.
LAN Ethernet Connector and Indicators
The Ethernet interface is an RJ45 connector with two LED indicators:
GREEN LED:
Solid Green indicates Ethernet link is up
Blinking Green indicates Tx / Rx traffic is traversing the port.
ORANGE LED:
Solid Orange indicates 100 Mbps link speed
Off indicates 10 Mbps link speed.
E1 Interface Connectors and Indicators
The E1 interface is an RJ45 connector with two LED indicators:
GREEN LED:
Solid Green indicates E1 port is enabled and traffic is traversing the port
Off indicates E1 port is disabled.
ORANGE LED:
Solid Orange Indicates E1 link error has occurred
Off indicates no alarms or failures.
The Orange LED indicates one of the following alarms has occurred:
E1 LOS, LOF, AIS or RAI alarm

WAN Ethernet Interface
The Ethernet interface is an RJ45 connector with two LED indicators:
GREEN LED:
Solid Green indicates Ethernet link is Up
Blinking Green indicates Tx/Rx traffic is traversing the port.
ORANGE LED:
Solid Orange indicates 100 Mbps link speed
Off indicates 10 Mbps link speed.
AC Power Socket and Switch:
The AC power supply operates with an input voltage range of 85V to 264V AC.
DC Power Socket and Switch:
The DC power supply operates with an input voltage range of -36V to -72V DC.
2-4 IP Configuration, important considerations
The IP address, subnet mask and default gateway are configured using the console port.
N.B The LAN port and WAN port IP addresses are on the same subnet.
N.B. The WAN port and NMS port IP addresses must be on different subnets.
2-5 Interface Configuration, important considerations
The LAN Ethernet port is normally data rate limited to ensure that it doesn’t affect the E1
circuits. The 16 data rate limits available are 50K, 100K, 150K, 200K, 250K, 300K, 350K, 400K,
800K, 1.6M, 3.2M, 6.4M, 12.8M, 25.6M, 51.2M and 100M.
Each E1 port can be enabled or disabled. The E1 LEDs are lit when the E1 channel is enabled.

The Jitter Buffer is used to compensate for packet delay variations between two devices, and the
jitter buffer size has 8 settings of 11, 23, 40, 75, 99, 145, 192 and 239 ms based on the standard
Ethernet frame size of 1518 bytes. The default jitter buffer size of 23ms corresponds to sufficient
buffering to compensate for 11.5ms of packet delay variation in each direction.
2-6 Fault Reporting
Active E1 alarms can be displayed by executing the CLI command almall. The alarms are
interpreted as follows:
E1LOS: Loss of E1 signal from the equipment connected to the E1 port.
E1AIS: AIS alarm received from the equipment connected to the E1 port.
PWLBIT: RAI alarm received from the equipment connected to the E1 port.
PWRBIT: Packet loss has occurred at the remote Ethernet WAN port.
PWSEQNUMERR: Packets received out of sequence at the local Ethernet WAN port.
JBUFEMP: Jitter buffer empty has occurred. (Possible reasons could be due to WAN
port Ethernet link down or pseudowire ID mismatched.)
JBUFOV: Jitter buffer overflow has occurred.
2-7 Default Factory Settings
The PacketLINK default factory settings are shown below.
CO device
(Factory Defaults)
NMS port IP address 192.168.1.11
NMS port subnet mask 255.255.255.0
Default gateway 172.16.1.2
WAN port IP address 172.16.1.1
WAN port subnet mask 255.255.255.0
LAN to WAN port bandwidth 400Kbps
2-8 Using the CLI to Configure the Unit
2-8-1 Using the Console Port
To use the console port, configure your terminal as follows:
115200bps, 8 data bits, no parity, 1 stop bit, no flow control
2-8-2 Using Telnet
The PacketLINK units support Telnet service for remote configuration via the command
line interface. However the Telnet port number has been changed to port 8888 due to the
security issues with default port 23.
PacketLINK User Manual

To telnet to a PacketLINK device (with default settings) from your computer, connect your
computer to the LAN port with an Ethernet cable, then follow these steps:
Step 1: Configure your computer IP address as 172.16.1.100 and subnet mask set to 255.255.255.0
Step 2: On the command terminal of your computer, type telnet 172.16.1.1 8888.
2-8-3 Using the CLI
The commands available via the console port or via Telnet are the same.
Login details:
Password: admin, logs you in as a basic user
CLI> passwd
Enter Password: gciadmin, logs you in as an administrator which is required for most
configuration changes
See section 3 for the list of CLI commands.
2-8-4 Save Configuration
After changing the device settings, please execute the csave CLI command to save the new
settings to the device. This will prevent configuration loss if the device is rebooted or power
cycled.
2-9 Setting up a Working Configuration
The following instructions will configure a working TDM over IP network including the settings
in the table below. This network will offer a single E1 connection from the E1 clock master
unit (which should be connected to the CO device) to the E1 clock slave unit (which should be
connected to the CPE device).
CO device
(Factory Defaults)

The gci command will re-initialize the CES (Circuit Emulation Services) engine. The cdisp
command will display the configuration. Note that the IP Addr, Net Mask and GW are the
settings of the NMS port (out-band). The NMS port’s IP must reside on a subnet different from
the WAN port. The WAN port is the Ethernet trunk which will carry the CES between two
PacketLINK units.
The SrcAddr (MAC) for this unit’s WAN port is automatically generated from the WAN IP
address (CTC OID+last three bytes of IP address). The channel settings require addressing the
remote unit via its MAC address. Therefore, we will need to know each PacketLINK unit’s MAC
in order to do the configuration. The SrcIP is the IP address assigned to the WAN Ethernet port.
We will leave this PacketLINK’s LAN and WAN settings as they are (and call this the CO unit).
We’ll configure the matching unit differently (and call it the CPE unit).
This setting example will only configure the Ch1 E1 link. The CLI can have scripts pasted,
avoiding repeated keying of data and possible mistakes keying.
Text may be pasted into PuTTY by using [shift + Insert] key combination. TeraTerm uses
[Alt+V].
Example scripts are provided in Section 5 which configure all E1 ports. These scripts can be
modified offline by engineers and used for quick configuration in the field.
2-9-3 CPE unit TCP/IP configuration
Connect the PC COM port to the console port on the other PacketLINK unit. This will be our
CPE unit for the test. We will update the NMS management and WAN IP configuration, note
the source MAC, configure CES on the CPE device and then go back and do the CO unit’s CES
configuration.
