This requirement will replace essential Local Telecommunication Services (LTS) and Long-Distance (LD) that are currently provided on a low-speed time-division multiplexed (LSTDM) circuit with session initiation protocol (SIP) circuit. All connectivity requirements and features currently transported over the existing LSTDM must be migrated to an emulated SIP path without loss of capabilities. This PWS is for managed SIP trunks. This LTS/LD will support the installation 24 hours a day/seven days a week/365 days a year (24/7/365).
