You have completed the LIS Trunk Group Types Module. Here’s a recap of what you’ve just learned:

1. Local Interconnection Service (LIS) is generally provisioned as two-way trunking.
   
   
2. Exceptions that allow one-way trunking are based upon certain billing, signaling, and network requirements.
   
   
3. CLECs must have a separate trunk group for each of the following types of communications traffic. Each trunk group uses either Multi-frequency (MF) or SS7 Signaling protocols.
   • Local/EAS Traffic (SS7 Generally)
   • Combined Trunk Group to the Access Tandem for Exchange Access and Jointly Provided Switch Access (SS7 Generally)
   • Directory Assistance (MF)
   • 911/E911 Services (MF)
   • Operator Services (MF)
   • Mass Calling (choke network) (MF)

4. There are four additional Trunking features that go beyond the basic LIS Trunking options. These include:
   • 64 Clear Channel Capability (CCC)
   • Host/Remote in same Local Calling Area (LCA)
   • Multiple LCA Host/Remote
   • Single Point of Presence (SPOP)
