Section 9, ATT-TP-76400 DETAIL ENGINEERING REQUIREMENTS

AT&T January, 2012

• Equipment cross-connect point.

• Electrical Protection.

• Test and Cable Access

3. DISTRIBUTING FRAME TYPES

3.1. Protector Frames

3.1.1 Protector frames (PF) may be either conventional or modular.

3.1.2 Protector frames are provided for the protection and termination of outside plant copper cable

pairs. These frames have no provisions for cross-connections, and are used in conjunction

with separate distributing frames. Outside plant cable pairs are terminated on protector

blocks on the PF. A cable is then placed from the protector block on the PF to a

corresponding terminal block on the MDF. The outside plant cable pairs on the MDF can

then be cross-connected to Carrier Communications Space equipment terminations

elsewhere on the MDF. The use of separate Protector Frames (PF’s) generally facilitate

higher density MDF configurations since more connector blocks can be mounted on the MDF

than protector blocks.

3.1.3 A protector frame only provides termination and protection capabilities for outside plant cable

pairs.

3.2. Modular Distributing Frames

3.2.1 Modular distributing frames currently in service include the below listed products. The

existing product may be grown to the completion of the next zone or end of lineup.

• Lucent Technologies ESS Modular Distributing Frame (Non-Standard -

Manufacturer Discontinued)

• COSMIC I - Common Systems Main Inter-Connecting Frame with separate

Protector Frame (Non-Standard - Restricted Use, growth only)

• COSMIC II -Common Systems Main Inter-Connecting Frame with integrated

Protector Frame (Non-Standard – Restricted Use, growth only)

• CODS – Carrier Communications Space Distribution System, Emerson Network

Power (Non-Standard)

• PORTA Systems - CAM DF (Non-Standard)

• Reltec Systems – COS II (Non-Standard)

• Robotic Frame – ADF (Non-Standard, growth only)

3.2.2 Growth to existing Modular Distributing Frames shall be the CommScope COSMIC I or II for

all modular installations and applications, subject to the limitations noted in ATT-002-216-

025, Switching IDG, Tab 11, and ATT-PAN-20011072, Restricted Use PAN for Avaya

COSMIC Frames (Now CommScope).
