The Cisco AS5300/Voice Gateway includes three expansion

slots. One slot is for a Quad T1/E1/PRI feature card and the

other two can be used for voice or modem feature cards.

Since a single Voice Feature Card can now support up to

48/60 voice calls, the Cisco AS5300/Voice Gateway system

can support a total of 96/120 voice calls.

The default memory conﬁguration for Cisco

AS5300/Voice Gateway is with 16MB of system Flash and

64MB of shared DRAM. The use of these Voice Feature

Cards also requires IOS release 12.0.2XH or later.

Ordering/Configuration Details

For ease in ordering, simply order AS5300-96VoIP-A. It

is a pre-conﬁgured Cisco AS5300/Voice Gateway (included

parts shown in Table 5). AS5300-120VoIP-A is the (E1)

120 voice channel counterpart.

Table 5 AS5300-96VoIP-A includes:

Note: If DC is required, AS53-DC-PWR can be ordered

as an additional option. If redundant power is required,

AS53-AC-RPS or AS53-DC-RPS can be ordered as an

additional option.

Table 3 Cisco IOS Software and QoS Features and Beneﬁts Summary

Table 4 Cisco AS5300/ Voice Gateway Feature Card Technical Speciﬁcations

Feature Beneﬁt

IP Precedence The Type of Service (ToS) ﬁeld in an IP header provides three settable precedence bits. Voice trafﬁc should be conﬁgured with IP precedence of 5.

This capability allows the network to prioritize voice packets above other trafﬁc, thereby assuring highest voice quality over congested network.

Queuing Mechanisms Queuing mechanisms include WFQ, priority queuing and custom queuing. These are conﬁgurable Cisco IOS software capabilities that reserve

appropriate bandwidth and prioritize voice and fax trafﬁc to ensure transparent delivery of toll-quality voice and fax.

CAR The committed access rate (CAR) feature performs both packet classiﬁcation and bandwidth management functionality. The packet classiﬁcation

features let users partition network trafﬁc into multiple priority levels or classes of service (CoSs). The network operator can deﬁne up to six CoSs

using the three precedence bits in the ToS ﬁeld in the IP header. The operator can then use the other QoS features to assign appropriate

trafﬁc-handling policies, including congestion management, bandwidth allocation, and delay bounds for each trafﬁc class.

WRED WRED features provide network operators with powerful congestion-control capabilities designed to provide preferential treatment for

premium-class trafﬁcundercongestion situationswhile concurrentlymaximizingnetwork throughputand capacityutilizationand minimizingpacket

loss and delay.

RSVP RSVP allows Cisco voice gateway to request/ reserve required bandwidth for a call.
