Inleiding
The IP Communications High-Density Digital Voice/Fax Network
Modules are the latest addition to the Cisco Systems IP
Communications suite of solutions. The IP Communications
High-Density Digital Voice/Fax Network Modules deliver high-density
digital voice connectivity, high-density WAN connectivity, analog
voice connectivity, and conferencing and transcoding capability in
a network module form factor. The network modules provide
enterprises, managed service providers, and service providers with
the ability to directly connect the public switched telephone
network (PSTN), traditional telephony equipment (such as private
branch exchange (PBX), key systems, analog telephones, and fax
machines), and WAN to Cisco 2600XM, Cisco 2691, 2811, 2821, 2851,
Cisco 3700 Series and Cisco 3800 Series Access Routers for either
IP Communications capabilities or pure toll bypass. The IP
Communications High-Density Digital Voice/Fax Network Modules
flexibly operates within two different Cisco AVVID (Architecture
for Voice, Video and Integrated Data) IP Telephony environments-the
Cisco CallManager system with Survivable Remote Site Telephony
(SRST) or Cisco CallManager Express. The network modules can be
integrated with these IP Telephony solutions in a Multiservice
Access Router, to provide a complete IP Communications solution for
full service branch customers.
Features
-
Rich set of features are
delivered on a single network module form
factor
-
Features such as
data WAN connectivity, high-density digital
voice connectivity, analog voice connectivity
and conferencing/transcoding are supported on a
single network module form factor, allowing
customers to utilize other network module slots
for other applications. A single NM-slot
platform can be deployed for small offices,
providing a cost-effective solution for IP
telephony.
-
Tightly integrated into
the Cisco Multiservice Access Routers
-
The IP
Communications High-Density Digital Voice
Network Modules are tightly integrated into the
Cisco Multiservice Access Routers, providing a
single IP communications solutions for the
full-service branch office. The Cisco
Multiservice Access Routers run Cisco IOS
Software, incorporating advanced
quality-of-service (QoS) features, intelligent
network queuing, and standards-based
encapsulation providing efficient direct
transport of both voice and fax over IP, Frame
Relay, and ATM networks.
-
Efficiently provides
analog and digital voice connectivity to the PSTN and
traditional office equipment
-
Analog and digital
voice connectivity are supported in a single
network module, enabling customers to
efficiently provide flexible and reliable
connectivity to public or private switched
telephone networks, and phones, faxes, PBXs,
and key systems.
-
Integrated data WAN and
digital voice connectivity
-
Voice and WAN data
is integrated on the same T1 interface,
providing a cost-effective way of delivering
PSTN and data WAN access for small branch
offices.
-
Supports higher-densities
of digital voice connectivity
-
Supports up to a
maximum of four T1/E1 ports in a single network
module slot for digital voice connectivity,
ideal for offices deploying toll bypass
(transporting voice and fax traffic across the
WAN to reduce or eliminate toll
charges).
-
Displays next-generation
robust, scalable and powerful digital signal processor
(DSP) technology
-
Features the latest
digital signal processing technology that can
support higher call densities per DSP, and more
flexibility in channel allocation per DSP. Up
to four PVDM2 slots are supported per network
module, providing scalability of 4-120 channels
per network module. These DSPs can be shared
among multiple IP Communications High-Density
Digital Voice/Fax Network Modules that are
installed in a Multiservice Access Router. DSPs
on the motherboard on the Cisco 2811, 2821,
2851, 3825 and 3845 Integrated Services Routers
can also be used with the NM-HDV2 network
modules.
-
Built-in and
easily-configurable T1/E1 ports
-
The convenient
built-in ports can be easily configured for
either T1 or E1 operation, providing
flexibility when ordering, provisioning and in
multi-national enterprise deployments.
-
Scalable and flexible for
enterprise office requirements of any size
-
The IP
Communications High-Density Network module is
supported on the Cisco 2600XM, 2811, 2821,
2851, Cisco 2691, Cisco 3700 Series and Cisco
3800 Series Access routers, providing a broad
range of selection depending on branch office
sizes and communications needs. The network
module can be reused as the platforms scale,
delivering investment protection.
Specifications
-
2-port FXO voice/fax
interface card [universal card for all countries]. Also
supports analog Centralized Automated Message Accounting
(CAMA) on any port.
-
FXO port is used to connect
to PBX or key system, or to provide off-premise
connections to PSTN. Supports battery reversal detection
and caller ID. These VICs can be software configured to
work in all countries. Also used to connect to analog
CAMA trunk to provide dedicated E-911 service (North
America only).
-
Voice Port-Specific
Features
-
FXS and FXO:
Provide battery polarity reversal detection and
initiation for disconnect supervision and
far-end answer supervision.
-
ISDN BRI network
side and phantom power: The VIC2-2BRI-NT/TE
provides the ability to connect a PBX/PABX
configured as user side directly to the router.
Also provides phantom power to accommodate
equipment that requires it.
-
Analog CAMA trunk
connection: The VIC2-2FXO and VIC2-4FXO provide
the ability to connect to analog CAMA trunks
which provide dedicated E-911 services. Each
VIC port can be individually configured as an
FXO or a CAMA port via Cisco IOS
Software.
-
Per port disable:
Allows disabling of any single port without
affecting any other port on the same VIC or
NM.
-
LED indicators for
voice processing resources and port
status.
