SN10100 Overview
The SmartNode 10100 is a carrier-grade media gatway for smaller service providers looking to drive conver-
gence between TDM and IP networks, replacing multiple devices for signaling, connnectivity, and media
transcoding with a single device.
The SN10100 enables the delivery of
VoIP services by bridging voice traf-
fic between the public switched tele-
phone network (PSTN)---based on
time-division multiplexing (TDM)--
-and IP networks such as the Inter-
net. Service providers are adding
VoIP capabilities to their networks,
whether to reduce costs when inter-
connecting with other carriers, to cost-effectively build out their network footprints, or simply to transport
voice traffic across their IP backbones. Whether sitting at the network core or at the edge, SmartNode media
gateways enable service providers to introduce VoIP into their networks while maintaining the quality and the
reliability of traditional TDM networks.
Features
•
TDM Interfaces
Service providers, whether providing local, long-distance or international voice services, are interconnected
with a multitude of other providers using T1/E1/J1 links. It is critical for service providers to be able to rap-
idly establish new interconnections without having to always deploy new devices. SmartNode 10100 Series
media gateways therefore offer flexibility and can be configured to support T1/E1/J1 interfaces.
•
Signaling and Control Protocols:
Just as flexibility in the selection and deployment of TDM links is a key requirement for service providers,
the need to support multiple signaling protocols across various carrier partners is just as important. Each
SN10100 media gateway provides support for the concurrent use of ISDN, SS7/C7, CAS (R2), SIP, and
SIGTRAN signaling in the same device. The ability to provide both switching and conversion across multi-
ple TDM and IP signaling protocols at once is paramount to enabling the operational flexibility and cost
savings that drive service providers to expand their carrier relationships and converge their networks.
In parallel with the TDM and IP signaling protocols mentioned above, SN10100 devices also support the
H.248 media gateway control protocol, which enables any H.248-compliant 3-party softswitch to control a
media gateway. While the softswitch manages call control interactions, the SN10100 handles transmission
of call media as well as any required transcoding.
•
Media Handling
Service providers will use one or more codecs on their VoIP networks according to their desire to save band-
width, to provide a certain level of voice quality, or simply to interoperate with other VoIP devices or pro-
viders. The ability to support multiple different concurrent codecs and to allocate them in real time based
on traffic is the key to delivering true network convergence.
SmartNode 10100 gateways feature extensive support for various wireline, mobile and IP telephony audio
formats, delivering seamless transcoding in real-time. The media gateways ship with support for G.711,
G723.1, G.726, and G.729ab right out of the box, with no additional license fee required. They also offer
