FieldDescription
MultiplexingDefines the way in which different protocols are
handled within a DSL virtual circuit. You an choose
between Logical Link Control (LLC) encapsulation (also
called LLC-SNAP) or Virtual Channel (VC) multiplexing
(also called VC-Mux).
QoS TypeSelect the DSL Quality of Service (QoS) method that
your ISP uses on your line: Unspecified Bit Rate (UBR),
Constant Bit Rate (CBR), Real-Time Variable Bit Rate
(RTVBR), or Non-Real-Time Variable Bit Rate (NRTVBR).
CBR provides the best guarantee of low latency; UBR
provides none, but is typically used for most broadband
data services.
4
Pcr Rate—When QoS is set to CBR, VBR_RT, or VBR_NRT,
•
enter the Peak Cell Rate (PCR) in cells per second.
•Scr Rate—When QoS is set to VBR_NRT or VBR_RT, enter
the Sustained Cell Rate (SCR) in cells per second.
•MBS—When QoS is set to VBR_NRT or VBR_RT, enter the
MBS in cells per second.
•CDVT—When QoS is set to CBR, VBR_NRT or VBR_RT,
enter the CDVT in cells per second.
VPI/VCI Auto DetectUse to enable or disable automatic detection of the VPI
and VCI values that identify your line to the ATM
network. The Virtual Path Identifier (VPI) and Virtual
Channel Identifier (VCI) are values used to identify your
line to your ISP's ATM network. The SRP will
automatically detect DSL services offered on the
following VC pairs: 1/32, 0/38, 0/35, 8/35, 0/43, 0/51,
0/59, 8/43, 8/51, 8/5.

Adding a Subinterface
Use the WAN Interface List page from the Internet Setup window to add a
subinterface to the SRP. These options are the same as those for configuring a
main WAN interface except you cannot configure an Ethernet subinterface for
PPTP or L2TP.
The SRP supports multiple logical interfaces per physical port. For Ethernet ports,
VLAN interfaces are created as part of an IEEE 802.1p trunk. Multiple PVCs may be
created on ADSL interfaces.
The SRP supports up to 5 VLANS which can be used as either Local Area VLANs
or WAN subinterfaces. Up to four PVCs can be configured on an ADSL interface.
STEP 1 To add a new logical Internet connection, select the top level WAN from the
Internet Setup page and click the Add (page) icon. The Internet Setup window for
the new Internet connection opens.
4
STEP 2 Choose the connection type required by your Internet Service Provide (ISP) as
defined in the Ethernet WAN Interface Settings table.
STEP 3 Choose an MTU option from the drop-down list. Unless a change is required by
your ISP, we recommend that you set the MTU method to Auto, which allows the
voice system to automatically choose the size. The default size is 1500 bytes.
To specify another MTU size, choose Custom from the drop-down list and enter
the size in bytes. The standard size for Ethernet networks is 1500 bytes. For
PPPoE connections, the standard size is 1492 bytes.
STEP 4 Click Submit to save your changes.

Failover and Recovery
An Internet connection can be established through the WAN port or a wireless
modem plugged into the USB port. See www.cisco.com/go/srp500 for more
details on compatible USB modem devices.
While both Ethernet and a USB modem may be connected, only one can be used
to establish a link at a time. Whenever the Internet connection fails, the SRP
automatically attempts to bring up another connection on another interface. This
feature is called Failover. When the original Internet connection is restored, reverts
to using this path and drops the backup connection. This feature is called
Recovery.
STEP 2 Click Enabled to enable Connection Recovery.

When enabled, the SRP sets the Ethernet interface to the highest priority and also
enables Interface Connection Failover. If the Internet connection fails, the SRP
automatically attempts to bring up the mobile network connection on the USB
interface (if available). Whenever the Internet connection recovers, the SRP
automatically reverts to using this instead of the backup interface.
NOTE Mobile Connection Mode must be set to Auto to use Ethernet Connection Recovery.

Port Forwarding
Use the Port Forwarding page if your network hosts network services (Internet
applications) such as web, email, FTP, video conferencing or gaming. For each
service, Internet traffic is forwarded by application (IP port) to the internal servers
that host these services.
Port Forwarding enables the SRP to route packets addressed to the WAN
interface for a specific application port, or port range, to an internal device on the
local area network. For example, if you have a web server on the SRP LAN, you
can set up port forwarding for all requests to port 80 to be translated and sent to
the internal web server IP address.
After clicking Add Entry, you can create another entry for another network service.
To edit an entry, click the Edit (pencil) icon.
NOTE To ensure correct forwarding of traffic, local servers must either be configured with
a static IP address, or be assigned a reserved IP address through DHCP. Use the

Configuring Voice Services
This section describes how to configure your SRP to meet the customer’s
requirements for voice services. It includes the following topics:
•Understanding Voice Port Operations
•Managing Caller ID Services
•Silence Suppression and Comfort Noise Generation
•Configuring Dial Plans
•Secure Call Implementation
Understanding Voice Port Operations
The SRP520 has a number of voice ports that allow calls to be made from locally
connected analog handsets or fax machines by using SIP based Internet phone
services. In addition to the four handset (FXS) ports, the SRP also has a single line
(FXO) port that can be used to place calls to the telephone network in the event of
broadband or even SRP failure.
Note: The SRP520 line port is a passive interface that connects the PSTN line with
FXS port 1 during failure conditions. Calls cannot be routed dynamically to this
interface under normal operating conditions.

The SRP maintains the state of each call made through the FXS interface and
makes the proper reaction to user input events (such as on/off hook or hook flash).
Because the SRP uses the Session Initiation Protocol (SIP), it is compatible with
most Internet Telephony Service Provider offerings.
SRP Voice Features
The SRP is equipped with fully featured, programmable voice ports that can be
custom provisioned within a wide range of configuration parameters. The
following sections describe the factors that contribute to voice quality:
•Supported Codecs
•SIP Proxy Redundancy
•Other SRP Voice Features
Supported Codecs
The SRP voice ports support the following codecs:
CodecDescription
G.711 (A-law and mu-law)Very low complexity codecs that support
uncompressed 64 kbps digitized voice
transmissions at one through ten 5 ms voice frames
per packet. These codecs provide the highest
narrow-band voice quality and uses the most
bandwidth of any of the available codecs.
88Cisco SRP500 Series Services Ready Platforms Administration Guide (SRP520 Models)
Configuring Voice
Configuring Voice Services
6
G.726-32Low complexity codec that supports compressed
32 kbps digitized voice transmission at one through
ten 10 ms voice frames per packet. This codec
provides high voice quality.
G.729aITU G.729 voice coding algorithm used to
compress digitized speech. G.729a is a reduced
complexity version of G.729 requiring about half the
processing power of G.729. The G.729 and G.729a
bit streams are compatible and interoperable, but
not identical.
The administrator can select the preferred codecs to be used for each line. See
Audio Configuration, page 171.
In addition, negotiation of the optimal voice codec sometimes depends on the
ability of a device to match a codec name with the codec used by the far-end
device. You can individually name the various codecs so that the SRP can
successfully negotiate the codec with the far-end equipment. For more
information, see Audio Configuration, page 171.
SIP Proxy Redundancy
In typical commercial IP Telephony deployments, all calls are established through
a SIP proxy server. A typical SIP proxy server can handle thousands of
subscribers. It is important that a backup server be available so that an active
server can be temporarily switched out for maintenance. The SRP supports the
use of backup SIP proxy servers (through DNS SRV) so that service disruption is
minimized.
An easy way to support proxy redundancy is to configure your DNS server with a
list of SIP proxy addresses. The SRP can be instructed to contact a SIP proxy
server in a domain named in the SIP message. The SRP consults the DNS server
to get a list of hosts in the given domain that provides SIP services. If an entry
exists, the DNS server returns an SRV record that contains a list of SIP proxy
servers for the domain, with their host names, priority, listening ports, and so on.
The SRP tries to contact the list of hosts in the order of their stated priority.
If the SRP is currently using a lower priority proxy server, it periodically probes the
higher priority proxy to see whether it is back on line, and switches back to the
higher priority proxy when possible. SIP Proxy Redundancy is configured in the
Line pages (1–4) in the Services Ready Platform Configuration Utility. See Line
Pages (1–2), page 156.

Configuring Voice
Configuring Voice Services
Other SRP Voice Features
The following table summarizes other voice features provided by the SRP.
FeatureDescription
Silence SuppressionVoice Activity Detection (VAD) with Silence
Suppression is a means of increasing the number
of calls supported by the network by reducing the
average bandwidth required for a single call. VAD
uses a sophisticated algorithm to distinguish
between speech and non-speech signals. Based
on the current and past statistics, the VAD
algorithm decides whether or not speech is
present. If the VAD algorithm decides speech is
not present, the silence suppression and comfort
noise generation is activated. This is
accomplished by removing and not transmitting
the natural silence that occurs in normal two-way
connection. The IP bandwidth is used only when
someone is speaking. During the silent periods of
a telephone call, additional bandwidth is available
for other voice calls or data traffic because the
silence packets are not being transmitted across
the network.
Comfort Noise Generation provides artificiallygenerated background white noise (sounds),
designed to reassure callers that their calls are
still connected during silent periods. If Comfort
Noise Generation is not used, the caller may think
the call has been disconnected because of the
“dead silence” periods created by the VAD and
Silence Suppression feature.

or fax passthrough.
minimize the impact of variable network delays.
This process is known as jitter buffering. The size
of the jitter buffer adapts reactively to suit
changing network conditions.
The SRP has a Network Jitter Level control
setting for each line of service. The jitter level
determines how aggressively the SRP tries to
shrink the jitter buffer over time to achieve a lower
overall delay. If the jitter level is higher, it shrinks
more gradually. If jitter level is lower, it shrinks
more quickly.
Adaptive Jitter Buffer is configured in the Line
pages. See Line Pages (1–2), page 156.
Secure CallsA user (if enabled by service provider or
administrator) has the option to make an outbound
call secure in the sense that the audio packets in

reversal and no DTAS.
ETSI DTMF—CID only. DTMF sent after DTAS (and no polarity reversal) and
before first ring.
ETSI DTMF With PR—CID only. DTMF sent after polarity reversal and DTAS and

Managing Caller ID Services
There are three types of Caller IDs:
•On Hook Caller ID Associated with Ringing—Type of Caller ID is used for
incoming calls when the attached phone is on hook. See the following figure
(a) – (c). All CID methods can be applied for this type of CID.
•On Hook Caller ID Not Associated with Ringing—Used to send VMWI
signal to the phone to turn the message waiting light on and off (see Figure
1 (d) and (e). This is available only for FSK-based CID methods: (Bellcore,
ETSI FSK, and ETSI FSK With PR).
•Off Hook Caller ID—Used to deliver caller-id on incoming calls when the
attached phone is off hook (see the following figure). This can be call
waiting caller ID (CIDCW) or to notify the user that the far end party identity
has changed or been updated (such as due to a call transfer). This is
available only for FSK-based CID methods: (Bellcore, ETSI FSK, and ETSI
FSK With PR).

STEP 1 Ensure that you have enough bandwidth for the uplink and the downlink.
STEP 2 To optimize G.711 fallback fax completion rates, set the following on the Line tab
6
Optimizing Fax Completion Rates
Issues can occur with fax transmissions over IP networks, even with the T.38
standard, which is supported by the SRP. You can adjust several settings on your
SRP to optimize your fax completion rates.
•For G.711 fallback, it is recommend to have approximately 100 kbps.
•For T.38, allocate at least 50 kbps.
of your SRP:
•Network Jitter Buffer: very high
STEP 3
•Jitter buffer adjustment: disable
•Call Waiting: no
•3 Way Calling: no
•Echo Canceller: no
•Silence suppression: no
•Preferred Codec: G.711
•Use pref. codec only: yes
If you are using a Cisco media gateway for PSTN termination, disable T.38 (fax
relay) and enable fax using modem passthrough. For example:
