countries, refer to the Multiservice Applications

 

 

Command Reference.

 

 

 

4

Router(config-voiceport)# compand-type{a-lawu-law}

Selects a companding type for this voice port.

 

 

 

5

Router(config-voiceport)# connection {plar stringtrunk

(Optional) Specifies either the trunk connection or the

 

string}

private line auto ringdown (PLAR) connection. The string

 

 

value specifies the destination telephone number.

 

 

 

6

Router(config-voiceport)# music-thresholdnumber

(Optional) Specifies the threshold (in decibels) for

 

 

on-hold music. Valid entries are from –70 to –30.

 

 

 

7

Router(config-voiceport)# description string

(Optional) Attaches descriptive text about this voice port

 

 

connection.

 

 

 

Fine-Tuning ISDN Voice Ports

Depending on the specifics of your particular network, you may need to adjust voice parameters involving timing, input gain, and output attenuation for voice ports. Collectively, these commands are referred to as voice-port tuning commands.

Note In most cases, the default values for voice-port tuning commands will be sufficient.

To fine-tune ISDN voice ports, use the following commands beginning in privileged EXEC mode:

Step

Command

Purpose

1

Router# configure terminal

Enters global configuration mode.

 

 

 

2

Router(config)# voice-port{shelf/slot/port:D}

Identifies the voice port you want to configure and enter

 

{shelf/slot/parent:port:D}

voice-port configuration mode.

 

 

 

3

Router(config-voiceport)# input gain value

Specifies (in decibels) the amount of gain to be inserted at

 

 

the receiver side of the interface. Acceptable values are

 

 

from –6 to 14.

 

 

 

4

Router(config-voiceport)# output attenuation value

Specifies (in decibels) the amount of attenuation at the

 

 

transmit side of the interface. Acceptable values are from

 

 

0 to 14.

 

 

 

5

Router(config-voiceport)# echo-canel enable

Enables echo-cancellation of voice that is sent out the

 

 

interface and received back on the same interface.

 

 

 

6

Router(config-voiceport)# echo-canel coverage value

Adjusts the size (in milliseconds) of the echo-cancel.

 

 

Acceptable values are 16, 24, and 32.

 

 

 

7

Router(config-voiceport)# non-linear

Enables non-linear processing, which shuts off any signal

 

 

if no near-end speech is detected. (Non-linear processing

 

 

is used with echo-cancellation.)

 

 

 

8

Router(config-voiceport)# playout-delay{maximum

Specifies the amount of time in milliseconds configured

 

millisecondsnominal milliseconds}

for the playout delay buffer.

 

 

 

9

Router(config-voiceport)# timeouts initial seconds

Specifies the number of seconds the system will wait for

 

 

the caller to input the first digit of the dialed digits. Valid

 

 

entries for this command are from 0 to 120.

AS5800 specifications

Cisco Systems has long been a leader in the networking and telecommunications field, and its AS5800 series of routers exemplify this tradition. The AS5800, along with the AS5850, AS5350, AS5400, and AS5300, provides robust solutions for service providers and enterprise-level networking applications. Each of these models has distinct features and characteristics that cater to the evolving demands of internet traffic and data processing.

The Cisco AS5800 is designed for high-capacity routing and optimized for broadband services. It supports a wide range of services, including voice, data, and video applications, making it a versatile option for service providers looking to deliver integrated solutions. It is equipped with advanced quality of service (QoS) features that ensure bandwidth is allocated effectively, holding strong even under heavy traffic conditions.

In comparison, the AS5850 offers superior processing capabilities and is typically utilized in larger-scale implementations. This model supports high-density interfaces, allowing numerous connections without compromising performance. Its architecture includes enhanced MPLS (Multiprotocol Label Switching) support, enabling more efficient traffic management and better utilization of network resources.

The AS5350 is known for its scalability and energy efficiency, ideal for voice-over-IP (VoIP) and media gateway applications. It supports various telephony features, such as protocol interworking and transcoding, making it a preferred choice for organizations focusing on digital voice technologies. The AS5300, while slightly older, continues to be a valuable asset for less demanding networks, offering reliable performance with VoIP capabilities and basic data applications.

The AS5400 bridges the gap between high-performance routing and operational efficiency. It incorporates Cisco's proprietary technologies to ensure seamless connectivity and robust failover systems. This model is highly regarded for its security features, protecting network integrity and providing peace of mind for businesses relying on sensitive data transfer.

Overall, Cisco’s AS5800 series showcases a progressive evolution of routing capabilities with enhanced features tailored for resilience, scalability, and performance. These routers not only address the technical needs of modern networks but also strategically position organizations for future growth in an increasingly digital world. Each model, with its unique attributes, continues to support the varied demands of global communication infrastructures.
