DOCSIS 2.0/3.0 Cable-Embedded Enterprise Session Border Controllers (ESBCs) 
As a leading ESBC provider, InnoMedia is uniquely positioned to provide cable operators the only DOCSIS cable modem integrated solution in the industry.

All the cable modem (CM) embedded ESBCs in the InnoMedia ESBC product family support Smart-DQoS™ and employ a unique CM-ESBC synchronization scheme that offers high reliability and minimum down time.

Smart-DQoS™
InnoMedia’s exclusive Device-initiated DQoS technology enables edge devices to intelligently initiate and manage DQoS UGS service flows based on user and signaling events without the need for PacketCable Multimedia.  Smart-DQoS™ instantly allows end-to-end QoS without having to wait for network infrastructure modifications. A simplified Smart-DQoS™ signal diagram is given below:

 Smart-DQoS
  1. ESBC → AS: Application Signaling
  2. AS → CMTS: Gate-Set
  3. CMTS → AS: Gate-Set-Ack (GateID)
  4. AS → ESBC: Application Signaling (GateID)
    • If GateID is not available → DQoS Lite
  5. DQoS:
    • ESBC → CMTS: DSA (GateID)
    • CMTS → ESBC; DSA Ack (ResourceID)
Importance of Smart-DQoS™
  • In cable networks where PacketCable Multimedia (PCMM) is not available, Smart-DQoS™ allows the utilization of DQoS to guarantee QoS-ensured SIP trunking services.
  • In cable networks where PCMM is available, Smart-DQoS™ may result in cost saving by not requiring PCMM initiated (thus, license-based) DQoS sessions.
CM-ESBC Synchronization
  • Integration of Cable Modem and ESBC into one device allows both components to communicate  →  close coupling yields powerful network architectural advantages
  • Allows ESBC to recover quickly if CM undergoes connectivity issues → minimizes ESBC downtime
  • ESBC will send DHCP DISCOVER after the following CM-related events to ensure CMTS retains ESBC MAC address in its CPE list:
    • ‘Clear Cable Modem Reset’ command from CMTS to CM
    • Loss of RF Sync (with or without T4 timeout)
    • CM Image Upgrade
    • CM Reset (through CLI or SNMP)
  • CM reset will cause soft reboot of ESBC
    • However, ESBC reboot does NOT cause CM to reset
esbc8528_tmb ESBC8528-4B – is the ideal demarcation solution to deliver Telephony to Enterprise Customers. It seamlessly enables SIP-based Voice over IP by resolving traversal and compatibility problems with IP-PBX’s and IP-Phones through existing network firewalls. It makes offering SIP Trunking services a breeze by normalizing SIP traffic between the IP-PBX in the enterprise network and the cable operator by providing SIPConnect adaptation and Low-level SIP Header Manipulation.
