What quota does communication engineering use to make crystal heads?

Two quotas, TXL7-045 and TXL7-046, are used to make crystal heads in communication engineering. In the budget quota of communication engineering, the table shows: quota code (TXL7-045), project name: 4 pairs of twisted-pair (distribution frame side) unshielded connection, unit (strip), mechanic (0.06 working days). Quota code (TXL7-046), project name: 4 pairs of twisted pair (distribution frame side) shielding, unit (belt), mechanic (0.08 working days). Of the above two quotas, TXL7-045 is used for non-shielded wire connectors, while TXL7-046 is used for shielded wire connectors.
