of T1/PRI or E1/PRI termination used by the service provider [network provider] and how close
it is to the MDF, the following tools and supplies are also needed. The T1 or PRI trunk is usually
connected to the standard RJ-48C modular jack provided on the T1M or T1M-2 module. See
page 5-29 for more information.
• For T1/PRI trunks terminated on RJ-48C jacks near the MDF or for E1/PRI trunks
terminated on RJ-45 jacks near the MDF:
