Hi (again)
What was the '835 710 splicing machine' used for?
Found it on e-pay, and thought it looked interesting. I am not bidding on it, I am just curious what it is.
Thanks,
Joe

Modular splicing Here's from Google. Basically they were to terminate 25 pair at one time, instead of one pair at a time.

Joe, it is used for the splicing of outside plant cables. As Bill said, instead of splicing one pair at a time, this system allows a splicer to lace 25 pairs into a module and crimp/cut/splice them with one throw of a handle. A HUGE labor-saving system that was developed in the 70's.
3M has pretty much bought this system. It was first developed by Western Electric. After the multiple transitions of AT&T, Avaya abandoned this segment of the industry and other manufacturers took over. PSI was the most predominant, a WECO sub that made their 2- type ("Waffle") splice closures.
Most major telcos use either the original 710 system or 3M's original MS2. Splicing by the pair is pretty much a thing of the past except for maintenance of old plant.

I never liked them. I thought it made a splice so big that you needed a garbage pail to fit around it.
But that's just my $0.02. Don't pay any attention to me. I'm not crazy about electronic key systems much less VOIP.
Gimme that old time telephony......

I too thought they made an ugly splice. I hated them in pedestals.

We still splice everything pair by pair. The only exception is in large splice cases where space is an issue or in DLC cabinets. Granted, most of the cable we work with is smaller count cable. Splicing by pair does make troubleshooting/testing easier though, IMO.

One thing they did have going for them was you could do half taps when reusing customer plant cable and not even interrupt service on existing circuit.We always used the 3M mini modules and that saved considerable space.
