Gateway Feature Summary

 

 

 

 

Feature

 

Description

 

 

 

Interoperability

 

The gateway provides a high degree of interoperability with other H.323

 

 

compliant gateways, gatekeepers, terminals, proxy, and Multipoint Control Unit

 

 

(MCU) products by being based on the H.320 standard and H.323 protocol stack.

 

 

Web-based management

The gateway features the gateway interface. This is a web interface used to

 

 

configure and monitor the gateway. You can view and modify all aspects of the

 

 

gateway configuration from a remote location using a Java-enabled web browser.

 

 

SNMP management

The gateway features Simple Network Management Protocol (SNMP)

 

 

management that supports all aspects of monitoring, diagnostics, configuration,

 

 

and trapping.

 

 

 

Diagnostics

 

The gateway features front and rear panel LED indicators that display status for

 

 

the unit. You can also access remote diagnostics of the unit through the gateway

 

 

interface, Telnet, SNMP, or a serial port.

 

 

Network load balancing

The gateway supports load balancing on the network by communicating with a

 

 

gatekeeper through H.323 RAI (Resource Available Indication)/RAC (Resource

 

 

Available Confirmation) messages.

 

 

T.120 data collaboration

The gateway supports data transfers in calls between ISDN and IP by using high

 

 

speed T.120 in HMLP and VarMLP formats.

 

 

Quality of service (QoS)

The gateway features configurable coding of media packets to achieve QoS

 

 

routing priority on the Internet Protocol (IP) network. The Type of Service (ToS)

 

 

bits of the IP datagram header can be configured for priority level.

 

 

 

Dial plan

 

The gateway supports a simplified dial plan for outbound dialing using a single

 

 

universal prefix. Using the dial plan, the gateway automatically detects the

 

 

capabilities received in the Setup message from the IP endpoint and sets the same

 

 

bit rate for the ISDN (or serial interface) side of the call.

 

 

Direct dialing and call routing

The gateway dial plan supports these direct dialing and call routing facilities:

 

 

Direct Inward Dialing (DID)

 

 

 

Multiple Subscriber Network (MSN)

 

 

 

Q.931 Sub-addressing Information Element

 

 

Internal and External Interactive Voice Response (IVR)

 

 

TCS4

 

 

Default extension

 

 

 

Access control

 

The gateway features password-controlled access to the gateway interface. You

 

 

can define up to ten different administrator access profiles for the gateway.

 

 

DTMF translation

The gateway supports translation between in-band Dual Tone Multi-Frequency

 

 

(DTMF) signals (on the ISDN side) and out-of-band H.245 messages (on the IP

 

 

side). DTMF translation occurs for voice and video calls.

3522 BRI specifications

Cisco Systems has long been a leader in networking and telecommunications equipment, and its BRI (Basic Rate Interface) and PRI (Primary Rate Interface) products are essential components in enabling businesses to manage voice and data communications efficiently. Notable models such as the Cisco 3522 BRI and 3527 PRI have earned recognition for their robust performance and versatile features.

The Cisco 3522 BRI is designed to deliver high-quality voice and data services over ISDN (Integrated Services Digital Network) connections. With two B channels for voice or data transmission, each supporting up to 64 Kbps, this device is ideal for small to medium-sized businesses that require reliable communication solutions while maintaining cost-effectiveness. The Cisco 3522 BRI supports multiple protocols, making it a flexible choice to adapt to various network environments.

On the other hand, the Cisco 3527 PRI supports up to 30 B channels, thereby significantly increasing the capacity for voice calls and data transfer. This scalability makes the 3527 PRI suitable for larger organizations that demand higher throughput and call handling capability. It operates over T1 and E1 lines, allowing businesses to leverage existing infrastructure while improving operational efficiencies. Additionally, the 3527's advanced features, such as call processing and load balancing, contribute to a seamless communication experience.

Both devices support a range of technologies that enhance functionality and performance. They are equipped with Call Admission Control (CAC) to optimize bandwidth use and reduce congestion during peak traffic. Cisco's VoIP technology, including features such as voice provisioning, fax over IP, and QoS (Quality of Service) mechanisms, ensures voice clarity and reliability.

Security is paramount, and both the 3522 and 3527 incorporate various protocols such as SRTP (Secure Real-Time Transport Protocol) to protect voice communications against unauthorized access. Furthermore, integration with Cisco's unified communications offerings allows for a more cohesive communication strategy, ensuring that users can take advantage of collaboration tools and data services.

In conclusion, the Cisco 3522 BRI and 3527 PRI models stand out with their impressive feature sets and technologies, making them an excellent investment for businesses needing reliable, scalable, and secure voice and data communication solutions. Choosing Cisco means embracing a future-proof solution that can grow with your organization's communication needs.
