Digital & IP Communication Server Solutions
Advanced digital and IP communications servers (CS)
Advanced digital and IP communications servers ESI Communications Servers
represent an innovative approach to digital and IP communications. The science
behind the switch is sophisticated in its simplicity: Design a platform with the
flexibility to support digital functionality with the ability to be configured
as a purely IP-based communications system. It’s ideal for any business that
wants the familiarity of digital telephony, the benefits of full
IP-to-the-desktop, or anything in-between.
ESI Communications Servers come in several models, to handle everything from the
modest call-handling needs of a small business to the large, customized needs of
the enterprise.
Digital & IP Support
Each ESI Communications Server — ESI-1000, ESI-600, ESI-200, or ESI-100 — is fully flexible. That means it can support traditional digital stations, IP-based, or any combination thereof that the customer requires. The largest model, the ESI-1000, supports a maximum system capacity of 1,128 communications ports.
An ESI Communications Server’s backplane, switching matrix, and main board are
designed to allow for a traditional digital installation or a VoIP configuration
in varying capacities. The non-blocking architecture increases station capacity
to a full complement of up to 816 telephones.
Feature-Rich
ESI Communications Servers share many common functions and features. Their innovative architecture integrates advanced IP functionalities, such as dedicated IP resources, the ability to support multiple Integrated VoIP Cards (IVCs), up to 96 Esi-Link channels, and remotely installed IP Feature Phones.
All ESI Feature Phone models, both digital and IP-based, provide advanced ESI features. ESI Cordless Handsets come in two sizes, each of which has three models to provide more connection choices — Digital, Local IP, and Remote IP. The 48-Key IP Feature Phone II supports Power over Ethernet (PoE). The optional VIP Softphone combines the functionality of a 48-Key IP Feature Phone II and the VIP Professional product in one PC-based phone.3 All ESI IP Phones are standards-compliant and operate with the customer’s local area network to promote Quality of Service (QoS).
