Understanding the 4-port Adapter
The Sylantro adapter must be installed at the client site to enable service for analog
and digital phones. The Sylantro adapter, installed at the customer site, converts
voice traffic into IP packets for transmission to the carrier network. The Sylantro
adapter turns your telephone into the ultimate “thin client” allowing the delivery of
advanced applications to your telephone.
The Sylantro adapter provides the following features to ensure the highest voice
quality possible over an IP network:
■G.711 CODEC, which converts analog voice traffic from the connected
telephones to IP packets and incoming IP packets from a media gateway or
another adapter back to analog voice traffic.

1Introduction to the Sylantro Communications System
1-4 Sylantro 4-Port Adapter Installation Guide
■Jitter buffers
The network can inflict a packet-by-packet time delay, which may be different
for each packet. Jitter buffers deliberately delay incoming IP packets in order to
create a fixed spacing, and also fix any out-of-order errors of the packets by
looking at the sequence number in the RTP frames and reassembling the voice
stream in the correct order.
■Echo cancellation
Echo is the reflection back to the sender of a telephone call. This echo is
eliminated by signal processors called echo cancellers. They sample the
transmission and echo signal and insert an out-of-phase cancellation signal into
the return channel, thus eliminating echo.
The adapter interfaces customer analog or digital telephones with the IP network
supplied by the service provider, as shown in Figure 1-1.

Sylantro 4-Port Adapter Installation Guide 1-5
Introduction to the Sylantro Communications System 1
For customers that have a mixed environment where both digital and analog devices
need to be supported, the 4-port digital adapter can be configured with three digital
ports and one analog port. This allows customers to use the same adapter for their
digital phones and have a fourth port available for an analog device like a fax
machine.
For more information on configuring the digital adapter with one analog port, refer
to “Connecting the Power” on page 3-4.
The following telephone devices are currently supported:
■Analog telephones (2500 set)
■Toshiba DKT2010-S digital telephone (10 button with speaker, no LCD)
■Toshiba DKT2010-SD digital telephone (10 button with speaker and LCD)
■Toshiba DKT2020-S (20 button with speaker, no LCD)
■Toshiba DKT2020-SD (20 button with speaker and LCD)
IP phones from various vendors are also supported but do not require a Sylantro
adapter.
Physical Description
The Sylantro 4-port adapter is available in a digital and an analog version. The
digital 4-port adapter supports four Toshiba telephones, or three Toshiba telephones
and one analog device (such as a telephone, FAX machine, or modem). The analog
4-port adapter supports four analog devices.
The front of the adapter is similar for the analog and the digital version. However,
the back of the analog adapter has one less port than the digital version. The front of
the digital adapter is shown in Figure 1-2.
Note: If the customer network is secured by a firewall, the client adapter
must be installed on the outside of the firewall to work correctly or the
firewall must be configured to allow SNMP, MGCP, and RTP packets.

The following interfaces are the same on both the analog and the digital adapter:
■One Ethernet 10/100BaseT port for connection to the client network.
■One RS-232 serial port for configuring the adapter.
■One Reset button for resetting the adapter.
In addition, there are five ports on the digital adapter, but only four ports are
available for connecting Toshiba telephones. The fifth port (POTS) on the digital
adapter can be used for an analog device provided that the TOSH 4 port is not used.
For more information, refer to “Setting Up a Digital Adapter to Support an Analog
Device” on page 3-4.
There is no fifth port on the back of the analog adapter.
Understanding the LEDs
Both adapters have Ethernet status LEDs, system status LEDs, and port activity
LEDs on the front of the chassis. The port activity LEDs are labeled according to
their port numbers and go on whenever the attached telephone goes off hook.
Table 1-1 describes the Ethernet status LEDs.
When the adapter is powering on,the system status LEDs provide informationabout
the bootup status, such as whether the adapter has connected to the Control Server.
Table 1-2 describes the system status LEDs during the bootup process.

Adapter Software
The adapter runs the VxWorks™ real-time operating system. Communication
between the adapter and the Control Server is handled using media gateway control
protocol (MGCP). Voice traffic is transmitted to and from a media gateway using
real-time protocol (RTP).
Aftertheadapterispoweredonandassignedan IPaddress,theadapterconfiguration
is downloaded automatically from the Sylantro Control Server located on the service
provider network. Minimal local configuration of the adapter is required.
The adapter software has the following capabilities:
■Automated configuration
