IES-1000 is a pizza box IP-based multi-service access node (MSAN). It has two slots for various combinations 

of DSL and VoIP line modules to provide ADSL2+, G.SHDSL and VoIP services to residential and business 

customers. It terminates the ATM traffic of DSL connections and POTS voice signals to make them IP 

packets and route them through IP networks. With the highly compact design (1U heigh), AC and DC power 

input as well as simple installation, IES-1000 can be deployed at Telco and SMB environment to meet all 

kinds of market demands.

With ADSL2+ line module, service providers can offer residential users high-bandwidth internet access, on-

demand entertainment services and IPTV services on a single network connection. The IES-1000 also offers 

businesses subscribers IP connectivity, VPNs, VLANs, high-quality video conferencing and legacy service 

interconnection with bandwidth up to 24Mbps per port. Moreover, it supports ATM-based 2-port bonding 

to provide even higher bandwidth to distant customers. The ADSL2+ line module is a sophisticated device 

fully compliant with existing standards and with modern features like energy-saving, excellent 

performance and transparent backward to ADSL/ADSL2 compatibility. 

With G.SHDSL technology, the IES-1000 is applicable for lease line replacement. Using the TC-PAM 

modulation technique, IES-1000 is compatible with other existing transmission technologies, allowing 

service providers to deploy at locations where broadband services already exist.

IES-1000 supports the new-generation G.SHDSL.bis line module to provide transmission rate up to 

4096kbps symmetrically in a single pair. It also comes with two 100Mbps Ethernet interfaces toward 

Ethernet aggregation network. One IES-1000 can accommodate two SAM1216-22 modules to support 32 

SHDSL connections. In addition, the SAM1216-22 supports ITU G.991.2 m-pair bonding in a physical layer 

manner. The m-pair bonding can be 2 or 4 pairs and the aggregated payload rate is around 16Mbps.

In addition to FAX and modem services,  VoIP line module provides a parallel and distributed media 

gateway architecture to empower VoIP services by taking advantage of POTS voice signals,. With the 

architecture, the line module serves up to 24 POTS ports. As part of the benefit, there is no throughput 

bottleneck or single-point failure issue in this architecture, The media gateway provides G.711, G.723, G.726, 

G.729a/b and T.38 codecs while RFC3261 SIP network signaling protocols is supported.
