High-Density Digital Voice/Fax Network Modules
for Cisco 2800/2900/3800/3900 Series
for Cisco 2800/2900/3800/3900 Series
The IP Communications High-Density Digital Voice/Fax Network Modules are an 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

2811, 2821, 2851, 2911, 2921, 2951, 3825, 3845 and 3925, 3945 Unified Communications
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 Unified
Communications (UC) environments—the Cisco Unified Communications Manager (UCM) system with
Survivable Remote Site Telephony (SRST) or Cisco Unified Communications Manager Express (UCME).
The network modules can be integrated with these IP Telephony solutions in a Unified Communications
Router, to provide a complete IP Communications solution for full service branch customers.

Cisco IP Communications solutions provide the means for integrating voice and data allowing users to take
advantage of services such as IP telephony, integrated services, and toll-bypass. These solutions allow enterprises,
managed network service providers, and service providers to reap the advantages of Unified Communications such
as lower operating costs and increased productivity. Cisco Unified Communications solutions also enable packet
voice technologies including voice over IP (VoIP) (including H.323, Media Gateway Control Protocol (MGCP), and
Sessions Initiation Protocol (SIP), voice over Frame, voice over ATM (including AAL2 and AAL5 adaptation layers).
The IP Communications High-Density Digital Voice/Fax Network Modules are an integral part of the Cisco Unified
Communications offering, delivering a versatile combination of digital voice, analog voice, and data capabilities in a
single network module form factor. They not only provide the IP telephony gateway to Cisco UC architectures for
calls to and from the PSTN and the WAN, but also allow enterprises to deploy networks with existing traditional
telephony equipment until they are ready to migrate to IP telephony. Features include high-density digital voice and
WAN connectivity up to four T1/E1 ports, analog voice connectivity up to four ports, and up to 50 conferencing and
transcoding sessions1. Enterprises can now deploy all these rich features on a single network module, enabling
connectivity to the PSTN, traditional telephony equipment such as PBXs, key systems, analog telephones, fax
machines, and the enterprise WAN.
