Width: 51 mm, Depth: 67 mm, Height: 17 mmThe Cisco\u00ae Packet Voice Digital Signal Processor Modules (PVDMs) enable Cisco 4000 Series Integrated Services Routers (ISRs) to provide rich-media capabilities such as high-density voice connectivity, conferencing, transcoding, media optimization, transrating, and secure voice for Cisco Unified Communications solutions. These new modules support unprecedented scale while allowing for a smaller solution footprint than ever before.<br \/>\nThe PVDMs support digital voice connections, conferencing, universal transcoding, and media optimization services:<br \/>\n&#8211; T1\/E1 voice: One of the primary uses of PVDMs is to packetize digital voice into IP packets to enable time-division multiplexing (TDM) digital voice applications.<br \/>\n&#8211; Conferencing: PVDM modules support ad hoc and meet-me conferencing with various codecs in conjunction with Cisco Unified Communications Manager and Cisco Unified Communications Manager Express.<br \/>\n&#8211; Universal transcoding: In conjunction with Cisco IOS\u00ae Software, the PVDMs support universal transcoding, which allows conversion from any supported codec to any other supported codec.<br \/>\n&#8211; Transrating: The PVDMs support transrating, in which the same codec is repacketized in order to connect dissimilar networks that have different codec packetization periods.<br \/>\n&#8211; Voice-quality management: The PVDMs perform compression, voice-activity detection, jitter management, and echo cancellation. The echo cancellation offered in the PVDMs has a tail length of 128 milliseconds and complies with ITU-T G.168.<br \/>\n&#8211; Energy savings: The motherboard PVDMs (PVDM4s) offer multiple power-saving modes, including a power-saver mode when the module is not in use. In power-saver mode, each PVDM4 can save up to 5 watts of power.<br \/>\nThe analog voice modules (FXS, FXO, and E\/M) and Basic Rate Interface (BRI) digital voice modules for the 4000 Series ISRs contain built-in, nonconfigurable digital signal processors (DSPs) and do not require any additional PVDMs for voice packetization.<\/p>\n","protected":false},"featured_media":10,"template":"","meta":{"site-sidebar-layout":"default","site-content-layout":"default","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":""},"product_cat":[2654,2670],"product_tag":[],"class_list":["post-6032","product","type-product","status-publish","has-post-thumbnail","hentry","product_cat-cisco","product_cat-network-cards-cisco"],"_links":{"self":[{"href":"https:\/\/infosystemservices.co.in\/index.php\/wp-json\/wp\/v2\/product\/6032","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/infosystemservices.co.in\/index.php\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/infosystemservices.co.in\/index.php\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/infosystemservices.co.in\/index.php\/wp-json\/wp\/v2\/media\/10"}],"wp:attachment":[{"href":"https:\/\/infosystemservices.co.in\/index.php\/wp-json\/wp\/v2\/media?parent=6032"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/infosystemservices.co.in\/index.php\/wp-json\/wp\/v2\/product_cat?post=6032"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/infosystemservices.co.in\/index.php\/wp-json\/wp\/v2\/product_tag?post=6032"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
